Thank you, Lei. Hello, everyone. This is Zhao Jiazhen. Thank you for joining our first quarter 2025 earnings call. Over the past few quarters, our high quality development strategy has entered a new phase. A series of initiatives such as fee reductions and merchant support programs have delivered solid results. Our fully committed efforts to build a win-win ecosystem are now generating tangible benefits to a broad base of users and tens of millions of merchants. Since the beginning of this year, as Chen Lei mentioned, to tackle new challenges together with our merchants, we have scaled up our commitment to high quality development and upgraded initiatives such as the 10 billion fee reduction program to the more comprehensive 100 billion support program. This upgraded strategy calls for the entire company to work together and fully devote ourselves to take on our social responsibilities as a platform at such a critical stage, providing merchants with greater certainty and offering consumers a more trustworthy shopping environment. On the supply side, under the 100 billion support program, we will further increase investments in high quality supply, expanding our support for high quality merchants from top and mid-tier merchants to small and medium sized. We are committed to focusing more on supporting the smaller merchants, which is the heart of critical steps toward achieving high quality growth. On one hand, we will continue exploring more fee reduction initiatives to help merchants lower costs and create more room for cost flexibility, business growth and innovation. On the other hand, will extend comprehensive support, including traffic resources, black label premium store programs, digital resources and technology capabilities to empower small and medium sized merchants, unlock their potential and drive broader, higher quality upgrades across the supply chain. Since the beginning of this year, our dedicated team for high quality merchant support program has visited frontline manufacturing bases such as cookware in Yongkang, women's footwear in Guangzhou, consumer electronics in Shenzhen, athletic shoes in Xinjiang and running shoes in Xin'an. We're pleased to see that the merchants and the broader supply chain have made notable progress in transformation with the platform's comprehensive support. Many merchants are transitioning from traditional OEM and distribution mindset towards user oriented and brand driven approaches. This shift has enabled them to pursue differentiated development path amid homogeneous competition. Moreover, fee savings are being reinvested into new product development, warehouse upgrades and supply chain transformation, accelerating high quality transitions across major industries. As a platform rooted in agriculture, our 100 billion support program will also enhance support for agriculture products. Recently, we officially launched the 2025 Duoduo Specialty Initiative. The first phase of the initiative has covered key agriculture regions. [indiscernible]. We're implementing tailored strategies across agriculture product categories such as local farm products, fruits, seafood and poultry, deeply integrating with regional agriculture industries and providing one on one guidance to small merchants. Through these initiatives, we aim to explore new models for agriculture product distribution, enhance value add and drive production and income growth across the agriculture industry. In the papaya producing region of Yunnan Gongzi, with the support from our platform, local merchants have developed a digital system for agriculture product operations, enabling automation across harvesting, listing, pricing, logistics, after sales services and traceability. This system addresses key industry pain points, such as unclear pricing and high spoilage rates, driving the transition from experience base to data driven operations and enabling the modernization of the traditional agriculture supply chain. On the demand side, the 100 billion support program has also launched several give back initiatives to benefit consumers. Our 10 billion program has introduced a new 10 billion merchant giveback program, rolling out RMB10 billion consumer coupons. Through dedicated campaigns such as the 10 billion coupon program and 10 billion duo [ph] of programs, we deliver additional coupons across all product categories to meet consumers' functional and personalized needs, while improving supply demand matching efficiency and supporting business growth for high quality merchants and brands. In addition, we further enhanced our direct discount program. We're fully safeguarding merchants' interest. We benchmark prices against the national subsidy program across multiple categories to provide real savings to consumers and stimulate consumer demand, aiming at compensating for the disadvantages under the national subsidy schemes and support merchants in strengthening their overall market position. While such investments may weigh on short term profitability, we believe they are necessary and worthwhile as they help create unique opportunities to achieve high quality growth for the small and medium sized merchants on our platform. In the face of a complex and evolving environment, we remain committed to building a business ecosystem in which users, merchants and the platform thrive together. We will continue to increase investments on various supply and demand side to help our merchants emerge stronger than these uncertainties, create more valuable experiences for consumers and generate greater positive impact for the society. I will now hand it over to Jun. She will provide you with an update on our Q1 financial performance.
