[Foreign Language]. Thank you, Sylvia, and thanks everyone for joining us. [Foreign Language]. The month around the end of 2022 was a challenging period for us as COVID-19 dynamics and the Chinese New Year temporarily have impacted our daily operations. Our offline centers closed for almost two months as the large number of teachers and students have to suspend classes due to pandemic restrictions or illnesses. Meanwhile, some employees were also unable to work for a period of time. To varying degrees, this affected our offline customer acquisition. Our online and offline course delivery and our offline center services. [Foreign Language]. In this challenging business environment, we achieved a positive operating cash inflow of RMB24 million and a non-GAAP operating income excluding share-based compensation expenses in the fourth quarter. This was due to our operational agility our stable OMO-based course delivery system and our consistent improvement of operational efficiencies. Our gross profit margin on the group level reached 58.4% in the fourth quarter, up 8.4 percentage point’s year-over-year. Specifically, our IT professional education business remained stable, with a gross profit margin of 73.2% rising by 8.1 percentage point’s year-over-year. Our IT-focused supplementary STEAM education business continued to demonstrate market resilience and business model scalability registering an enrollment growth of 17% and a gross profit margin of 48.6% in the fourth quarter, up 13 percentage point’s year-over-year. In addition, despite the challenges from external headwinds throughout 2022, we achieved a turnaround from a net loss to a net profit of RMB85.23 million and a non-GAAP net profit of RMB102 million for the year. As a result of the continuous upgrades in our operating model, deliver quality and service capabilities. [Foreign Language]. Our total net revenues amounted to RMB552 million in the fourth quarter, down 15.7% compared with RMB655 million in the same period of 2021 due to the factors I mentioned earlier. Segment-wise our IT-focused supplementary STEAM education revenue was comparable with that of the fourth quarter of 2021, while our IT professional education revenue declined by 31.6% due to the impact of macroeconomic headwind. [Foreign Language]. With respect to cost control during the period, we optimized our business management model to enhance operational efficiencies and effectively control expenses. In the fourth quarter, impacted by factors beyond our control, our revenue decreased. However, our cost decreased by 29.8% year-over-year, as a result, our gross profit -- our gross margin rose by 8.4 percentage point’s year-over-year in the fourth quarter. Additionally, operating expenses decreased by 15.7% year-over-year substantially narrowing our operating loss by 92.4% year-over-year to RMB4.57 million. Our non GAAP operating income, excluding share-based compensation expenses was RMB233,000, meanwhile we realized an operating income of RMB93.04 million for the full year of 2022, compared with an operating loss in 2021 as well as a non-GAAP operating income of RMB109.6 million. [Foreign Language]. Next, let me walk you through our IT-focused supplementary STEAM education. [Foreign Language]. In the fourth quarter of 2022, net revenue from our IT-focused supplementary STEAM education program was RMB334 million, comparable to RMB336 million we recorded in the fourth quarter of 2021. This represented 60.5% of our total revenue during the period, an increase from the fourth quarter of 2021. Enrollment increased by 17% from 151,300 in the fourth quarter of 2021 to 177,000 in the same period of 2022, thanks to our high quality courses and delivery as well as our growing brand recognition. Meanwhile, with steady revenue growth and effective cost control at our centers, our gross profit rose by 35.8% year-over-year in the fourth quarter and our gross profit margin climbed by 13 percentage points to 48.6%. [Foreign Language]. On the customer acquisition front, our total number of fee paying students in the fourth quarter of 2022 was 38,200, a decrease of 10.7% year-over-year as our student recruitment was affected by the temporary closure of our offline centers. However, our excellent course and delivery quality and our students' learning results in IT-focused supplementary STEAM education have translated into word-of-mouth referrals and an increase in a number of renewal students as a percentage of fee paying students, partially offsetting the decrease in customer acquisition due to limited vendor access. Meanwhile, thanks to our integrated online and offline course delivery system and our non-staff OMO service model we ensure high course and service quality to the maximum extent despite the constraints imposed on our operations in the fourth quarter. In the fourth quarter, enrollments increased by 17% year-over-year, notably the percentage of renewal students who have enrolled for over a year continued to exceed 78.7% in the fourth quarter. [Foreign Language]. Regarding the operation of our centers, although some of them suspended operations due to the pandemic in the fourth quarter, we managed to improve operational efficiency while ensuring course and service quality. This helps us to reduce operating costs and expand single center profitability. At the end of the fourth quarter of 2022, the total number of centers providing IT-focused supplementary STEAM education services declined to 213 from 238 at the end of the fourth quarter of 2022, a net reduction of 21 centers. At the same time, the number of students enrolled per center increased from 336 in the fourth quarter of 2021 to 805 in the same period of 2022. In the fourth quarter, average revenue per center grew by 7.8%. [Foreign Language]. Next, moving to our IT professional education business. [Foreign Language]. During the fourth quarter, the pandemic impacted societal mobility in general, affecting our enrollments and operations as well. To cope with the situation, we suspended the operation of some offline centers for a period. This had a significant impact on our operations in the fourth quarter. Specifically, net revenue for our IT professional education business dropped by 31.6% year-over-year. Of course, our centers have resumed full operations in since the Chinese New Year holiday. In addition, we continued to facilitate stable operations by reducing costs and improving operational efficiency. In the fourth quarter, the total costs and operating expenses of our IT professional education business decreased by 23.7% year-over-year. [Foreign Language]. Our society places more emphasis on digitalization and information-based development. We'll embrace new opportunities brought about by the digital economy during China's macroeconomic recovery. ChatGPT has set up a new wave of AI technology advancements worldwide and its core generative AI models will promote the deployment of new technology and influence how business and society develop. We always stay abreast of the latest cutting edge technologies and market demand and continuously innovate our courses, services and operations accordingly. Meanwhile, we have continued to explore the application of the latest technologies. Recently, we became one of the first approved ecosystem partners of the ERNIE Bot developed by Baidu. Through this collaboration, we will explore the application of smart dialogue technology in professional education, which marks the first application of the conversational language model in professional education in China. We believe that broader application and rapid development of AI technology are bound to drive the demand for high standard IT talent and that they will fuel the development of the IT professional education industry. We will continue to spend at the forefront of technological innovations in industry and continue to create value for our students and their employers with our industry leading courses and delivery services. [Foreign Language]. That concludes my review of the Company's operations for the fourth quarter and full year of 2022. [Foreign Language]. Next, I'll turn the call over to Ping, to walk you through our financials for the fourth quarter and full year of 2022.
