Thank you, Larry, and thank you, everyone, for joining our call today. I will now walk you through our operating and financial performance for the fourth quarter and fiscal year 2024. This year, we demonstrated a strong strategic perseverance in a rapidly evolving and changing market landscape, achieving key milestones in our business. As the scale of our business reaches new heights, we have established flexible and dynamic resource, allocation mechanisms to continuously calibrate and guide our approach to steer the business towards sustainable growth. We ended the year on a high note, with solid financial results and major business breakthroughs, further strengthening the competitive edge of our core operations. During the fourth quarter, our revenue grew by 82.5% year-over-year, reaching an annual peak and increased by 29.4% sequentially, driven by the continued expansion of our active user base and long-term accumulation of teaching excellence. Meanwhile, gross billings maintained strong growth momentum, rising by 69.0% year-over-year. These results not only underscore our business success in expanding market scale, but also highlight the increasing strength of our brand influence and growing market recognition. On the profitability front, a growing base of existing users contributed to improve margins, further supported by the economies of scale. As a result, loss from operations for the quarter narrowed significantly year-over-year. This progress reflects our success in maintaining a healthy unit economics model and driving greater operational efficiency, laying a solid foundation for long-term growth. For the full year, net revenues increased by 53.8% year-over-year to approximately RMB 4.6 billion, while gross billings grew by 68.1% year-over-year to over RMB 5.6 billion. We generated RMB 258.0 million in net operating cash inflow for the year. As of December 31, 2024, our total cash position, including cash and cash equivalents, restricted cash and short and long-term investments stood at RMB 4.1 billion. Excluding the impact of share repurchase, our cash reserves increased by RMB 183.9 million compared to the same time last year, ensuring ample financial flexibility to support business development and provide a sufficient margin of safety for our strategic investments. Next, I will walk you through the progress we have made during the quarter. Learning services contributed more than 95% of net revenues. Breaking it down, nearly 85% of total revenues came from non-academic tutoring services and other traditional learning services, representing a triple-digit year-over-year increase. Focusing on non-academic tutoring services, our new initiatives remain dedicated to driving continuous innovation in educational products and learning services to enhance teaching effectiveness and the overall learning experience. By introducing new products and diverse interactive course formats, we are constantly igniting students' interest in learning, fostering cognitive growth, improving practical skills cultivating critical thinking and instilling lifelong learning abilities. During the quarter, this segment sustained strong growth momentum, achieving triple-digit year-over-year growth in gross billings for the third consecutive quarter. Our ongoing refinement of both educational products and teaching approaches has also contributed to improved retention with retention rate for new students rising by more than five percentage point year-over-year. Our traditional learning services continue to maintain a leading position in the online education sector. On the product development front, we further enhanced our content mode by building a comprehensive multi-tiered ecosystem of teaching assistants and books to meet the diverse learning needs of students at different levels. Our self-developed book series has been adopted by schools across multiple provinces in China. This highlights the strong demand for our products and expand our brand presence and market reach. In terms of teaching quality and services, key performance indicators such as retention rates and user satisfaction remain at industry-leading levels, reaffirming the strength of our offerings and supporting sustained healthy growth of our business. The other crucial component of our learning services is educational services for college students and adults. Through strategic focus and streamlined optimization, core offerings in this segment gained robust growth momentum, contributing nearly 15% of total revenues in the quarter. We have leveraged AI technology to enhance the teaching model for our educational services for college students, significantly improving teaching efficiency and enabling a sustainable increase in the tutor-to-student ratio. Additionally, ongoing enhancements in product and service quality further optimized the overall user experience, leading to a steady rise in referrals and creating a self-reinforcing word-of-mouth effect. From a financial perspective, gross billings for this segment grew by high double-digit growth year-over-year this quarter, while revenue doubled compared to the same period last year. On a full year basis, both revenue and gross billings experienced rapid expansion. And for the first time, the segment hit profitability on an annual basis with operating net cash inflow reaching 3.5 times that of the prior year. This marks a major milestone in our path towards more sustainable operations. Our overseas test prep business continues to demonstrate its professional value. This year, we successfully helped students gain admission to Harvard, Columbia, Cornell and other Ivy/Avid [ph]League schools and other prestigious international universities, highlighting the effectiveness of our service offerings. These achievements stem from our deep understanding of user needs and our ongoing commitment to service quality and process excellence. Looking ahead, we will remain focused on the technological innovation and deepening user value to drive high-quality growth. By leveraging cutting-edge AI technologies, a diverse product portfolio and unique advantage of rich learning scenarios, we aim to deliver user-centric, personalized and high effective learning solutions establishing ourselves as the most trusted partner in every learner's journey.
