Hello, everyone. Welcome to Sunlands' Second Quarter 2023 Conference Call. Prior to commencing, I would like to kindly remind all attendees that the financial information referenced in this release are presented on a continuing operation basis and all figures are denominated in RMB unless explicitly specified otherwise. In Q2, our business showcased remarkable resilience and steady performance. Our second quarter net revenue has experienced a slight decrease compared to the previous quarter but exceeded the high end of our guidance range, reaching RMB526.4 million. Net income experienced a year-over-year increase, reaching RMB173.9 million in Q2, marking the ninth consecutive quarter of sustained profitability for our company. We still maintain a positive outlook for the upcoming second half of the year. Through proactive reassessment of our long-term strategic focus and implementation of a series of endeavors, our pursuit of developing valuable interest courses has continued to yield notable results. Specifically, our revenue in the professional certification preparation, professional skills and interest courses has surged by 32.7% year-over-year, and we have witnessed a 36.8% increase in new student enrollments in this sector. The robust market demands have instilled us with confidence, and we remain committed to seizing emerging opportunities actively, promoting innovation and improvement to meet the diverse needs of adult learners, and achieving sustained growth and development. Now let's turn to the performance of our major course programs. We persistently focus on optimizing the gross billing structure resulting in revenue generated from our post-secondary programs now contributing to less than 30% of our total revenue. We are content with the results of this structural change and remain committed to ongoing optimization in alignment with our strategic objectives, a sector that includes professional certification preparation, professional skills and interest courses stands as our primary focus, and it has been performing remarkably well…

This concludes Tongbo's prepared remarks. With that, I will turn the call over to our financial controller, Hangyu, to run through our financials.

The operating expenses decreased to RMB40.1 million or 11.4% year-over-year. Our net income margin increased 12.4 percentage points compared to the same period last year. Looking ahead, we'll keep our commitment to delivering value to our stakeholders and maintaining a competitive edge in the industry. Going forward, we are positive to long-term growth.

Cost of revenue decreased 34.8% to RMB59.5 million in the second quarter of 2023 from RMB91.2 million in the second quarter of 2022.
