Okay. Thank you, David. Hello, everyone. Thank you for joining our conference call. Our growth momentum continued in the second quarter with the gross billings coming in above the guidance. Our continued growth and improved operating metrics confirm our approach to concentrate our resources on existing markets. We will remain investing in markets where we see market potential and a benefit from an early mover advantage. In this existing markets, we will strengthen our localization efforts and maximize the potential from our online and offline branding activities. At the same time, we will continue to explore new markets. We remain well disciplined in our expense control and will keep tight budget control and a focus on optimizing our resources. We look forward to further net revenue growth in the coming quarters and remain committed to our sustainable growth approach. The second quarter also saw us completing our listing transfer to the NYSE American, the transfer of the listing has concluded a time of uncertainty, and we are now in full compliance with the listing requirements of the NYSE American, removing concerns of a potential listing. It is testimony to our commitment to existing and new shareholders and it also concludes our transformation from a Chinese education company to an international educator supporting students in all parts of the world to achieve their learning goals. In terms of technology, we believe that AI-powered tutors will transform online education and the winners will be those that can provide users with the most customized content and solutions. With that vision in mind, our technology team is working relentlessly to develop the integration of large language models such as Chat GPT in our products to optimize user experience. We will launch an engaging trial product for our young learners in due course. With that, I will now turn the call over to our CFO, Cindy.

Thank you, Jack. Our business momentum carried into the second quarter as net revenues were $6.3 million, representing 12.8% sequential growth. Gross margin for the second quarter was 78.4%. Gross billings grew by 21.0% quarter-on-quarter to $9.8 million, not only beating the guidance at the high end but also reflecting some early fruits of our localization efforts. Q2 operating expenses was $7.9 million, an increase of 14.5% compared to the last quarter. Specifically, this has been driven by Q2 sales and marketing expenses of $5.1 million or 15.0% sequential increase from Q1 due to increased investment in branding and localization such as increased local marketing and operational personnel as well as various marketing activity. Q2 product and development expenses was $0.7 million, a 4.8% sequential increase due to increased research and development projects. Finally, Q2 general and administrative expenses were $2.1 million, a 16.7% sequential increase compared to Q1, mainly due to one-off administrative factors. Overall, Q2 operating loss was $3.0 million while net loss was $2.9 million, up 15.6% and 11.3% sequential increase from Q1, respectively. Q2 GAAP and non-GAAP earning per ACS were negative $0.51 and $0.48, respectively. The Company's total cash, cash equivalents and time deposits were $21.6 million at the end of the second quarter. Advances from students were $21.0 million at the end of the second quarter. Looking forward to the third quarter of 2023, we currently expect net gross billings to be between $10.3 million and $11.0 million. The above outlook is based on our current market conditions and reflects the Company's current and preliminary estimates of the market and operating conditions and customer demand, which are all subject to change. This concludes our prepared remarks. We will now open the line for questions. Operator, please go ahead.
