Thank you, Alex. Now I would like to share with you more details on the development of each of all three business lines; including one, learning services and other, two content solutions and three, learning technology solutions during this past quarter. Please note that the financial data for each business line mentioned below is based on unaudited data for the quarter. First is the learning services and other, which primarily includes the learning programs we provide in various class sizes; both online and offline. This includes ADS small class, share.com, Think Academy and other learning services businesses. During the quarter, learning services and other accounted for approximately 70% of our overall revenue, maintaining its position as our largest revenue contributor. Within learning services, I'd like to first talk about enrichment learning programs, which aimed at helping with learners all around development. In the first quarter, we improved products and services of our existing programs, leveraging our expertise in users' learning journey, as well as our knowledge in pedagogical methodologies. In addition to our current programs, covering science and creativity, coding and programming and humanity and aesthetics, we also wrote out new programs such as international chess, rhetoric and natural science learning. In a time when COVID-19 continues to pose complexities for offline operations, our OMO model demonstrated its resilience. Many of our offline customers opt to take their classes online with us, mitigating the impact of the pandemic. As the pandemic normalizes, we believe that being online will be an inevitable trend for learners going forward. I'd also like to share some progress of our overseas learning services, which achieved a year-over-year triple digit growth rate in the last quarter. We operate under the Think Academy brand outside of the Mainland of China by providing diversified programs for K to 12 students. In the last quarter, in addition to learning centers, we already have in Singapore, the United Kingdom and the United States, we also started doing businesses in new locations, such as Canada. Moving forward, we expect Learning Services to remain our primary revenue contributor. At the same time, we'll proactively explore new opportunities in terms of program expansion domestically and market expansion globally. Secondly, content solutions is one of the initiatives we have explored in depth since the beginning of our transformation into a small learning solutions provider. With this business line, we offer academic and non-academic learning content in both print and digital formats by leveraging the broad content library we accumulated over the company's history, as well as the content acquired or licensed from our domestic and global partners. Total revenue generated from our Content Solutions business for the quarter accounted for more than 10% of the overall net revenue driven by product expansion and sales growth. As for products, a product format that has been particularly well received by our customers is Smart Books or [indiscernible]. Smart book is a product format where we embed videos on to print books. Operator, can you hear me?
