Thank you, Yolanda. Hello, everyone, and thank you for joining Zhihu Second Quarter 2025 Earnings Call. I am [ Victor Joe ], an AI- powered voice agent of Zhou Yuan. I am pleased to deliver today's opening remarks on behalf of Mr. Zhou Yuan, Founder, Chairman and CEO of Zhihu. We posted our third consecutive quarter of non-GAAP profitability, once again beating market expectations by a wide margin. Adjusted net income for the second quarter reached RMB 91.3 million compared to a loss of RMB 44.6 million in the same period last year, while gross margin expanded by approximately 3 percentage points year-over-year. These results highlight the strength of our disciplined operating strategy and the value of our AI-powered productivity gains. Zhihu's ecosystem continues to flourish with our trustworthy content and professional creators, enriching the experience for users and creators alike. In particular, leading experts continue to drive deeper engagements within the community, steadily amplifying the influence and strengthening the ecosystem. This increased engagement is clearly reflected in several key user metrics. While MAUs remained stable from last quarter, daily time spent, core user retention and high-tier creator engagement, all posted notable gains, both sequentially and year-over-year. Our expanding in-house AI capabilities and growing industry influence have reinforced our platform's unique value proposition as the go-to destination for professional trustworthy Chinese language content with an increasing number of users and creators flocking to the platform. Notably, our platform has emerged as the preferred launch pad for new AI technologies and products while becoming the leading network for AI talent and expertise.

As AI tools surge in popularity, professional contents from the Zhihu community is increasingly being cited by a growing number of leading large AI models and AI search engines. We are pleased to see Zhihu serve as a key source for our credible information and research, especially in practical use cases such as scientific education, consumer decision-making and career development. Moving forward, we will further enhance the user and create experience by integrating AI more deeply throughout our community by adding intuitive features like personal knowledge assistance. We will continue to test, refine and enhance our AI capabilities to amplify the value of Zhihu as trusted content and expert network across the broader Internet. We believe these efforts will establish our platform as a foundational source of reliable content for the Chinese AI ecosystem. Our persistent efforts to optimize the trustworthiness of our content system and foster greater creator engagement across the community continue to deliver tangible results. In the second quarter, average daily user time spent exceeded 39 minutes, reflecting a 15% year-over-year increase. Core user retention improved significantly, both on a sequential and year-over-year basis. While the depths of DAU content engagement increased quarter-over-quarter. This progress reflects our ongoing efforts to optimize community features and refine operational strategies throughout the year. Through AI integration, we've created a more user-friendly and reliable user experience, while strengthening connections among our users and key contributors. Over the past 14 years, we've developed and continuously refined Zhihu's content model building a robust foundation where professional content strives and consistently inspires trust, drives citations and encourages discussions online. In the second quarter, daily high-quality content creation increased by over 10% sequentially. AI has emerged as a key vertical with professional AI-related content, maintaining year-over-year growth of over 45% for 2 consecutive quarters. Recently, we've seen a growing trend of more and more frontline engineers and AI model developers openly sharing key insights that go beyond academic papers. This has made Zhihu a uniquely valuable community where new products debut in-depth discussions unfold, and knowledge is continuously built and preserved. Over the past months alone, Zhihu has been the go-to platform for top AI teams and the frontline developers to launch and discuss new technologies and products. For example, Moonshot AI unveiled the technical details of their Kimi K2 model with core developers actively engaging in Q&A sessions to break down the architecture and technical details. ByteDance's team also released their GR-3 robot model on our platform, accompanied by an exclusive article outlining their development principles and journey. The Trade team at ByteDance also shared a comprehensive overview of their model iteration process. In addition, Zhipu AI launched its GLM-4.5 model on our platform and Alibaba's [ QT's ] team released 3 consecutive models, sparking a series of vibrant community discussions. Even StepFun's co-founder, Yibo Zhu, chose Zhihu to thoroughly explain the design ideas behind the step 3 architecture. Through ongoing improvements to our content, ecosystem and algorithms, we continue to identify and suppress the spread of low- quality content, reducing its distribution by more than 98% year-over-year and over 59% sequentially. During the challenging annual Gaokao college entrance exam in June, when students are often overwhelmed with information and the need to make critical life decisions, Zhihu leverage is trustworthy structured content ecosystem to provide clear and practical guidance. Tools such as the Gaokao Data Hub offered data-driven support for application submissions while long table discussions such as career paths for humanities majors and how to navigate away from discouraged to majors brought together, expert voices offering valuable insights. Zhihu's university communities also supported students by sharing authentic firsthand perspectives about campus life. Professional creators form the backbone of our ecosystem. In the second quarter, daily active high-tier creators continued to grow sequentially, while the number of verified honored creators increased by 26% year-over-year. This is community continues to thrive with high-quality engagement. As of the end of June, over 16 million continuous learners and 3.65 million proficient creators on Zhihu engaged in science and AI-related discussions. Among those who are AI developers, over 56% hold a Masters or a doctoral degree. Nearly 40% are aged between 18 and 24 and 14% are senior technology professionals including company executives, CTOs and tech leads to provide a better experience for professional creators. We continue to optimize our ideas and column products. The upgraded ideas product now seamlessly aligns with the high-frequency creation workflow of professionals while encouraging interaction among users with shared interests. This led to a quarter-over-quarter increase of over 15% in both views and engagement in the second quarter. The column feature has strengthened connections among like-minded users resulting in a 45.7% quarter-over-quarter increase in daily visits. Additionally, more professional creators launched their own columns this quarter, fueling solid growth in the total number of columns. At the same time, deepening AI integration within our community has continued to expand our AI capabilities and service scope. In the second quarter, we launched a major update to Zhihu Zhida public knowledge base built on top of existing personal knowledge libraries. This update delivers a seamless AI interaction experience for creators and users across a wide range of reading, Q&A and search use cases. It has also further reduced AI hallucinations in professional domains. Within just 2 weeks of launch, users created hundreds of new entries on the public knowledge base. This momentum also supported the creation of additional private knowledge bases among users enabling them to consolidate and archive their search and research workflows. Moving forward, we will continue to develop Zhihu Zhida as an AI agent embedded within the community, serving as a comprehensive productivity suite for search, research, learning and content creation. We will further promote the open sharing of professional content within the Zhihu community and continue to strengthen the synergy between high-quality content, our trusted expert network and AI capabilities. We are thrilled to see that Zhihu Zhida has entered an exciting new stage of growth and innovation. Once it achieves critical penetration relative to overall platform traffic, with the user experience and onset quality reaching key milestones, we will seek to integrate it across our broader suite of products. Now let's move on to commercialization. In the second quarter, we maintained a dynamic balance between commercial growth and community integrity by proactively refining our product offerings and client mix. While still navigating an adjustment cycle, we are encouraged to see the year-over-year top line decline moderating with total revenue reaching RMB 716.9 million in the second quarter. We firmly believe these ongoing adjustments will lay a solid foundation for our sustainable long-term growth. Moreover, our evolving AI capabilities and content ecosystem will continue to enhance and expand our commercial services, reinforcing the virtuous cycle between commercial growth and community vitality. Let's turn to performance by segment. Our marketing services are progressing through the adjustment phase as planned and remain on track. In the second quarter, Marketing services revenue grew 13, 1% quarter-over-quarter to RMB 222.8 million, with the year-over- year decline narrowing substantially. We continue to crack down on low-quality marketing content, reducing its consumption by over 90% year-over-year during the second quarter. We also made meaningful progress in optimizing our client mix. Leveraging Zhihu as strong brand equity and influence, we expanded our enterprise-facing or [ 2B ] client base and diversified our commercial IP products and services tailored for top-tier clients. During the June, the 18th shopping festival, we launched the Smart Picks Expert Choice campaign, capitalizing on Zhihu's trustworthy content model and high-value user community. This initiative boosted brand awareness and highlighted products strength for leading brands such as [indiscernible], BYD, Roborock and [indiscernible]. Furthermore, our advertising product upgrades are accelerating, powered by our advanced AI capabilities. While the second quarter is typically peak season for e-commerce, our overall ad load significantly decreased from the same period last year, while CPM performance improved sequentially across most product categories. During the June the 18th shopping festival, users increasingly use our AI capabilities to make more informed purchase decisions reflected in the 190% year-over-year search in the Zhihu June the 18th Recommendation Search Index, the index for June the 18th purchase related searches on Zhihu Zhida grew by 61% quarter-over-quarter, and the average order value per user increased by 27% year-over-year. We are also building stronger connections between trusted content creators, high-quality content and products the number of content creators participating in product promotion grew by 10% year-over-year, while the volume of promotional content increased by 20% year-over-year. We continue to upgrade our CCS product which are quickly gaining traction among clients. Advertising spend from the gaming sector saw a fourfold increase year-over-year, while our client base expanded by 75% with ongoing improvements to our AI capabilities, we expect marketing services to recover more strongly in the second half, expanding our commercial potential and driving long-term value. And now for our paid membership business. In the second quarter, average monthly subscribing members totaled 13.2 million, with revenue reaching RMB 402 million representing a slight sequential decline of 3.8%. This was largely driven by our strategic emphasis on acquiring users with longer life cycles and higher ROI potential, which impacted new member sign-ups. Since the start of the year, we have focused on enhancing user stickiness and diversifying our paid content and business models. As part of this, we further expanded and upgraded the premium content formats and service offerings under Yanyan story. Notably, voice live streaming has seen steady growth in both user penetration and paid conversion rates since launch. In the second quarter, its ARPU significantly exceeded our expectations and continues to grow, reflecting strong user endorsement and the monetization potential it offers. The Yanyan story long form writing Marathon launched in May has generated thousands of high-quality submissions from creators within just two months significantly outperforming similar initiatives over the period. This highlights the distinct advantages our content creator ecosystem has and the growing mind share we hold among users in the long- form content space. This directly translates into extended user subscription cycles and build on our leadership in the short-form content space. Our commitment to premium paid content and support for creators has enabled Yanyan story to consistently deliver high-quality works that blend the literally richness with broad emotional appeal. This has allowed us to build a stable and robust content pipeline that is both well received by users and widely recognized across the industry. In June, Yanyan titles received 3 major awards in the 2024 China online literature influence ranking, [Foreign Language], further validating our content strategy and strengthening our foundation for IP development and monetization going forward. Momentum is also building in the commercialization of our original IPs. In the second quarter, revenue from IP licensing grew by triple digits both year-over-year and quarter-over-quarter. By the end of June, more than 40 premium short-form stories published on Zhihu had generated revenue through film and television licensing, among them, [indiscernible], Guiding All Souls [Foreign Language], No Time To Die, [Foreign Language] [indiscernible] the Birth of Queen. Together, dubbed the 3 Yanyan master pieces. Yanyan [indiscernible] were especially well received by audiences while attracting strong interest from film and television adaptation partners. Lastly, our vocational training business recorded revenue of RMB 62.1 million during the quarter, down 34.3% quarter-over-quarter. As we focus resources on high-performing course categories, and gradually phase out offerings with limited growth potential or lower profitability. This strategic focus is designed to improve overall business quality and long-term growth. Encouragingly, operating profit of the business for the quarter increased by an impressive 90% year-over-year, demonstrating the effectiveness of our operating strategy and execution. We continue to make steady progress in the broader strategic transformation of our vocational training business, powered by our high- quality content ecosystem and trusted creator network, we are transitioning from a traditional subject-based expansion model, focused on a few core categories to a more community-driven approach that fosters deeper social engagement and knowledge sharing. This will also unlock new monetization opportunities for professional creators. In support of this, we enhanced the creator experience and paid content ecosystem of our new column product this quarter. Since May, we have improved operations, product experience and algorithms to better support content creation and distribution. These efforts led to a more than 50% increase in shared column content from May to June. Creator user engagement also improved significantly. The growing demand for premium content further fuel the monetization of paid columns with GMV in June, increasing by over 34% month-over-month. For the remainder of the year, we will continue to drive the integrated development of high-quality content, a trusted creator network and AI capabilities, further reinforcing Zhihu's competitive moat in the AI era. As AI becomes more deeply embedded in our community, we aim to enable more intelligent, reliable experiences for users across a variety of scenarios on the commercial front, we will accelerate our product upgrades to better serve high-value users and professional creators, building a suite of solutions that enhance user trust and support stronger commercial monetization. Leveraging this foundation, we will further expand the reach of Zhihu as AI capabilities beyond our platform, offering our trusted content and services to a wider user base. We are confident that stronger synergies between our community and commercial ecosystems will reinforce Zhihu's value proposition as a trusted platform and unlock long-term sustainable growth. With that, I will hand the call over to our CFO, Wang Han, whose remarks will also be delivered through his AI voice agent. Han, please go ahead.
