Thank you, Sam. And thanks, everyone, for making time to join our earnings conference call today. In the second quarter, we continued to forge ahead our recovery path, made a challenging environment brought about by the lingering impact of the illegal products on the e-vapor industry. However, we worked hard to improve our product portfolio and operational efficiency. And we are happy to say that our efforts yielded positive results in both our financial and operational performance for the quarter. Before I go deeper into our second quarter efforts and performance, let me briefly update you on the recent market conditions. As we shared on our last call, the prevalence of illegal products in China have significantly impacted on the client-compliant product sales and slowed the industry's recovery in the positive -- in the post-regulatory era. In March, regulators took steps to maintain a fair and orderly market and initiated special action lasting over months to combat illegal products. Although these measures were somehow -- somewhat effective, they ended in April, and we have since seen a resurgence of illegal products in the market. As a compliant participant in the e-vapor industry, we have continued to strictly comply with regulations, concentrating on improving our products to cater to users' various needs and increase our competitiveness. Thanks to our growing portfolio of high-quality products and regulators crack down efforts, the overall market conditions have improved compared to earlier this year. And our sales improved quarter-over-quarter. However, the negative impact of illegal products continues to pose a challenge, and we participate in more bumps on our path to full recovery. This is especially true when considering the difficulties our global counterparts have faced under similar circumstance. Let's use the United States as an example. In 2020, California state lawmakers passed a law prohibiting menthol cigarettes and other flavored tobacco products. This law went into effect in late 2022. As a result, smokers have been looking for alternatives such as flavored e-vapors, which are becoming increasingly popular across the country. These products are available from both legal and the illegal sources. The legitimate manufacturers are working on developing and marketing California compliant products, but competing with the easy availability of flavored products in the market is difficult. In the same way, China's compliant e-vapor brands are losing market share to illegal flavored products. Although our compliant products offer better quality and safety, the playing field is not level. Illegal products becoming a broader range of flavors and at a lower cost since their manufacturers do not pay taxes. These noncompliant products are unregulated and lack quality and safety assurance, which harms the overall reputation of the e-vapor industry. Now over the illegal trade results in tax losses for the government and finds its way into young teenagers targets, given the shrinking size of compliant channels and fast-growing scale of the illegal channels filled by illegal products. Though we believe that regulators will limit the impact of these products in the long run, the presence in the market will impede our recovery in the short term. Nevertheless, we are confident that our premium products will continue to bring users trust and support. Adult smokers will realize the advantages of our products and develop new habits, which will ultimately boost our momentum. Now let's move on to our strategic efforts in the second quarter. First and foremost, we continue to enhance our product portfolio, incorporating users' feedback and maintaining high-quality standards. We are excited to announce that we've expanded our cartridges offerings from 15 in May to 20 in July. We have top-notch research and development capabilities, efficient supply chain management and strong quality control systems that the laws to produce high-quality products consistently. Our RLX physiochemistry lab enabled us to closely monitor the chemical composition of our e-liquid and aerosols ensuring that any potentially harm emissions are kept to the minimum. Additionally, we are broadening our scientific research to further enhance product safety and explore the possibility of greater harm reduction. Our expanded research will cover topics ranging from chemistry and biology to social science. At RLX, we prioritize user preference in highly valued consumer feedback, especially as we develop new products to meet the diverse needs while adhering to regulations. During the quarter, we continued to improve our user service management and systems to enhance our customer service teams' abilities and ensure that users receive the best possible experience. Additionally, we expanded our initiatives to address user feedback encouraging them to interact with us more extensively and offer more specific opinions and suggestions. Next, I would like to discuss our ESG initiatives. We recently released our third ESG report, highlighting our progress towards sustainability in 2022. At RLX, we believe that fulfilling our social responsibility is a key competitive advantages for our brand, which adult smokers trust. To guide our ESG efforts and disclosures, we performed several material analysis each year which examines various issues in relation to the importance in higher sustainable development and relevance to our stakeholders. In light of the introduction of regulatory policies and national standards for e-cigarettes. In 2022, we prioritized product innovation, harm reduction and product quality in this year's initiatives. In addition, our material analysis consider external stakeholders, continue to emphasize on corporate climate actions prompting us to proactively formulate low-carbon development strategies and strengthen our climate-related information disclosures. We also prioritized public health in our ESG efforts, investing in technological innovation to minimize the impact of e-vapor products on the public. Through our 1+4 Research Chain, we conduct systematic scientific evaluations and research reduction. Validating these efforts, our subsidiary, Shenzhen Wuxin Technology was appointed as 2022 Guangdong Provincial Engineering Technology Research Center for new type atomizer intelligent atomizers and inhalation by the Department of Science and Technology of Guangdong province in December 2022. We are committed to realizing technology to advance public health initiatives and continuously refining our forward looking ESG strategy to benefit our company, the stakeholders and community for the long term. As we move into the second half of the year, we expect an uneven in pumping recovery. However, we believe our effective strategy, premium products, resilient business model in the core capabilities will guide us through the ever-changing market. We will deepen our commitment to offering compliant high-quality products to adult smokers, positioning RLX for long-term growth as we strive to create sustainable value for all stakeholders. With that, I will now turn the call over to our CFO, Chao Lu. He will elaborate further on some of our last quarter's initiatives and go over our operational and financial results in more detail.
