Thank you, Brian. This is Su Peng. I will handle the question first. I think aligned with our strategy of achieving the positive full year operating profit in the near future, we focus on strong demand services, which are scaling back on the low return customer acquisition efforts during the last summer -- during this summer, and we believe that the healthy and sustainable development is more essential for the long-term success. And as you may notice, Youdao Lingshi definitely is a strategic priority for our business. Although there are some short-term headwinds, we remain optimistic about the medium and long-term growth. We expect to sustain strong demand for the online learning services in the coming years. Ensuring the financial health of our business, we will facilitate the development of the learning service, particularly in Lingshi. We believe that is our long-term strategy. We believe that increasing our market shares over the midterm to the long term will primarily come from providing the differentiated and high-quality products and services to the users and improving their learning outcomes. We think our flagship products offer a unique combination of AI tiered learning videos and comprehensive learning consulting services. Through the AI enhancements and ongoing product upgrade, we enabled the users to achieve personalized education, improve learning efficiency and outcome. The comprehensive services, including the learning diagnostics, learning path planning, paired learning video, AI creates recommendations and AI collection and the categorization of the students' mistakes, learning consulting services, one class study experience and also the AI college admissions advisers. I think that's the kind of the full services generated and driven by our AI. We will definitely continue to invest in our products and services, which have strengthened our users' loyalty, evidenced in the upgrade in retention rate for the first quarter. The current retention rate, we just give you a little bit color for the Lingshi, has already hit about 70% by now, although the retention period has not finished yet. It's almost over, up about over 5% compared with the same period of last year. Looking ahead, I think I'm confident in Lingshi development for the next year. On one hand, we will continue to focus on our personalization, prerecorded video learning, leveraging our AI capabilities and upgrade and enhance our users' learning experience. On the other hand, we will explore more offline opportunities, offering offers and service to our customers. I think that's our priority. And in the long term, the last point, we expect we will increase the investments on the product upgrade and also the customer acquisition following the strategy of the total companies. Thank you.
