Amid the pandemic's resurgence and macroeconomic weakness in the second quarter, we achieved RMB 114.6 billion of net income, representing a four percent increase year-over-year. The increase was primarily driven by our consistent emphasis on operating effi ciency and the solid execution of our business strategies, as we remain steadfast while navigating the company through external uncertainties. We were also pleased to see our continued efforts to optimize our product mix and expand our course portfolio rewarded with improving operational results, reflected in a 13.4% year-over-year increase in our new student enrollments, and a reduced year-over-year decrease in course billings. We accomplished this by acquiring students from a wider range of age groups with higher sales efficiency, as we cut down our sales and marketing expenses by 13.8% year- over- year. The results highlight our organizational resilience and reinforce our confidence in our strategy to achieve balanced growth and profitability. During the second quarter, with the massive pandemic outbreaks in several major cities severely disrupted business operat ions across the array of industries. The pandemic also resulted in the cancellation of many qualification exams, affecting demand for our professional certificate courses and leading us to seek other pockets of opportunity to increase profitability in this segment. Furthermore, amid the complex macro environment, business took a more conservative approach in their operations and emphasized cost reduction and efficiency improvement more than ever, with the goal of enhancing their risk resistance. Against the backdrop, consumers were more prudent about purchasing discretionary goods. For example, they may temporarily delay their self-improvement plans within this period. To combat the lingering external uncertainties in the macro environment, we also prioritized cash flow management and focused on profitability, generating business while continuing to improve our cost efficiency. Despite that, many people remained enthusiastic about honing their skills, hoping to elevate their overall competence within the highly competitive job market. Others also sought ways to shake off pandemic inertia, such as attending online courses, resulting in surging demand for our skill courses. As such, we seized this o pportunity to deliver an enhanced learning experience to our students and develop the new skill training courses to address a broader range of students' needs, helping our students improve their career flexibility and competitiveness in the job market, or turn a skill into a side hustle to see them through tough times. As a result, our course billings for professional certification and skills programs in the second quarter grew by 82.9% year-over-year, driven by a 94.9% year-over-year increase in new student enrollments. The revenues generated by the programs also increased by 13.3% year-over-year. Furthermore, our extensive course resources, high teaching quality and efficient online learning platform have contributed to improve the student satisfaction and stickiness, as well as a higher referral rate. As we continue to optimize our product mix, we will keep developing premium courses covering in-demand skills and general interests, as well as industry-recognized credentials. With our established brand awareness in this field, diverse course choices, and quality course content, we are confident that we can continue to attract new students and capture additional growth opportunity presented by students' rising demand. For master's degree-oriented programs, new student enrollments and growth ratings decreased on the back of our strategic reduction of marketing activities and growing market competition as new players try to capitalize on this segment's enormous potential. Highly rated teaching staff, which is difficult to replicate for latecomers to the segment, is cons idered the main differentiating factor among industry players. Thus, we believe that our 19 years experience in exam preparation, experienced and well-received te aching staff and extensive learning resources will position us very cautiously compared to our competitors in the long run. Despite the intense competition and the complex macroeconomic environment, we are proud of the critical role that we have played in helping our students achieve individual success in the face of huge economic uncertainty. We remain committed to doing the right thing to maintain our influence in this field. For example, on June 18, we held our 5th MBA education promotion event with many top universities in China joining us to share their MBA admissions information. The event was a great success and attracted huge number of students to participate. In terms of government policies, we are encouraged by the Chinese government's support of diverse forms of education, as evidenced by the revised vocational education law adopted dur ing the meeting of the Standing Committee of the 19th National People's Congress on April 20. This was the first major reform in 25 years since the law was enacted in 1996. It upgrades the status of vocational education in China to be equally important as general education and encourages collaboration between schools and enterprises, while also supporting social participation in vocational education. The government is planning to adopt various measures to organize diverse forms of occupational education, such as training prior to employment, on-the-job training, re-employment training for the young unemployed and other special groups of people, which significantly enhanced our confidence in the industry. We will closely follow the government's policies and will remain steadfast in our contributions to China's effort to improve its workforce skills and employment rate through occupational education. Finally, I'm pleased to state that in June, we declared a special cash dividend to share our success with shareholders following four consecutive quarters of profitability. Going forward, we will strive to create additional shareholder value by continuously improving our profitability and cash flow. At the same time, we remain focused on developing diverse skill and interest courses and enhancing our teaching and service quality to attract new students, with a target of bringing life-changing and fulfilling learning experience to our students. With that, I will turn the call to our CFO, Selena Lu Lv, to run through our financials. Thank you, Tongbo. Hello, everyone. Our second quarter results were in line with our expectations. We sustained bottom-line strength despite the 11.8% year-over-year decrease in net revenues as we strove for healthy and sustainable growth. During the quarter, we continued executing various initiatives to build a highly efficient and lean organization while optimizing our expense management, leading to a 32.4% year-over-year decrease in our operating expenses. Our cost efficiency improvements resulted in notable net income growth from RMB 22.1 million for the second quarter of 2021 to RMB 114.6 million for this quarter. Going forward, we are optimistic that our continued efforts to broaden our online course offerings, streamline our cost structure and dedicate ourselves to providing enhanced services to our students will ultimately enable us to realize long-term growth. Now let me walk you through some of our key financial results for the second quarter of 2022. All comparisons are year-over-year, and all numbers are in RMB unless otherwise noted. In the second quarter of 2022, net revenues were RMB 555 million, a decrease of 11.8% year-over-year. Cost- of- revenue decreased by 6.2% to RMB 91.2 million in the second quarter of 2022 from RMB 97.3 million in the second quarter of 2021. The decrease was primarily due to the decline in employee compensation expenses related to the cost of revenues. Gross profit decreased by 12.9% to RMB 463.8 million from RMB 532.2 million in the second quarter of 2021. In the second quarter of 2022, operating expenses were RMB 351.2 million, representing a 32.4% decrease from RMB 519.6 million in the second quarter of 2021. Sales and marketing expenses decreased by 34.8% to RMB 293 million in the second quarter of 2022 from RMB 449.1 million in the second quarter of 2021. The decrease was mainly due to, number one, lower spending on branding and marketing activities. Number two, declined compensation expenses related to our sales and marketing personnel. General and administrative expenses decreased by 9.7% to RMB 46.6 million in the second quarter of 2022 from RMB 51.6 million in the second quarter of 2021. Product development expenses decreased by 38.3% to RMB 11.6 million in the second quarter of 2022 from RMB 18.8 million in the second quarter of 2021. Product development expenses were mainly comprised of compensation expenses. Other income decreased by 41.8% to RMB 4.8 million in the second quarter of 2022 from RMB 8.2 million in the second quarter of 2021. Net income for the second quarter of 2022 was RMB 114.6 million compared with RMB 22.1 million in the second quarter of 2021. Basic and diluted net income per share was RMB 16.89 in the second quarter of 2022. As of June 30th, 2022, the company has RMB 727.5 million of cash and cash equivalents and RMB 138.7 million of short-term investments. As of June 30th, 2022, the company had a deferred revenue balance of RMB 1,998.1 million compared with RMB 2,348.2 million as of December 31st, 2021. Capital expenditures were incurred primarily in connection with IT infrastructure equipment and the leasehold improvements necessary to support the company's operations. Capital expenditures were RMB 0.3 million in the second quarter compared with RMB 7.8 million in the second quarter of 2021. Now for our outlook. For the third quarter of 2022, Sunlands Technology Group currently expects net revenue to be between RMB 520 million-RMB 540 million, which would represent a decrease of 9.3% to 12.6% year-over-year. This outlook is based on the current market conditions and reflects the company's management's current and preliminary estimate of the market, operating conditions and customer demand, which are all subject to change.
