Thank you, Xiaoping. This is Shun, Viomi's CFO. I will quickly translate Mr. Chen's remarks before providing an operational update and discuss our financial performance for the first quarter of 2020. Hello, everyone, thank you for joining our First Quarter 2020 Earnings Conference Call. Despite challenging industry conditions and ongoing macro uncertainties as a result of the COVID-19 outbreak, we successfully delivered better-than-expected results in the first quarter of 2020. Net revenues for the first quarter increased by 13.2% year-on-year to RMB766 million, demonstrating the resilient and diversified nature of our business as well as our strong execution capabilities. Since the beginning of the second quarter, our business and supply chain capabilities have largely returned back to normal. In addition, we have seen meaningful signs of an overall industry recovery. With these positive trends beginning to emerge, we have accelerated the execution of our growth strategy for this year under our 5G + IoT strategic framework. The development of 5G in China has accelerated rapidly. According to China 5G Economic Report 2020 released by China -- released by the China center for International Economic Exchanges, 5G users in China are expected to reach over 800 million by 2025. In March, the government proposed to speed up the establishment of 5G network infrastructure and expand application scenarios. The number of available 5G stations in China has reached over 200,000 by May, according to the data published by the Ministry of Industry and Information Technology of China. With the trend of increasing 5G network penetration, we believe this will be one of the key potential growth drivers of industry growth in the near term and beyond. We believe the upcoming 5G era will bring about 4 revolutionary technological enhancements in the IoT @ Home environment: product connectivity, algorithms, interactions and ecosystems, driving the evolution from product intelligence to scenario intelligence. Viomi has been dedicated to exploring new technologies and applications in the 5G + IoT space and expects to be at the forefront and the standard bearer of 5G + IoT for the home environment. Just last week, we hosted our 5G IoT Strategy and 2020 New Product Launch Event, where we outlined our vision and its product strategy for the imminent 5G + IoT era and emphasized our long-term strategic objectives. We introduced a number of new and exciting product lines across our product portfolio, including the state-of-the-art 21Face Interactive Smart Screen TV. The product will come in 4 sizes, including a high-end 75-inch model with 5G connectivity and 8G -- 8K resolution, delivering stunning life-like scenes. Equipped with industry-leading specifications, users will be able to enjoy next-generation content offerings with high-speed 5G connectivity. Supported by 3D interactive sensors, long distance sensors and a 1080p HD camera, the product enables natural gesture and motion control while integrating WiFi, Bluetooth, ZigBee and other protocols to deliver truly holistic IoT functionalities. The launch of this product will be an important milestone in the realization of cross-scenario and cross-screen interactions and completes our vision for the fully integrated and screen-filled IoT @ Home lifestyle experience. In addition to introducing the smart TV as an interactive interface for IoT @ Home, we also introduced our home private cloud service, Home SaaS concept, offering rich media streaming content, cloud storage and improved AI interaction services, bringing users an enjoyable seamless experience while protecting their privacy and data safety. The development of our home cloud service, together with other content and service offerings, will allow us to provide users more intelligent IoT solutions based on the integration of software services and IoT products, with the support of big data and 5G infrastructure, further expanding and enhancing the IoT @ Home experience and providing us with additional value creation opportunities. In addition, we announced several exciting next-generation products at the event, including new lines of water purifiers with revolutionary water purification technologies, such as the ROX 1,600 gallon water purifier product with unique next-generation large flux reverse osmosis capabilities. Other additions to our product portfolio include new series of our flagship 21Face large-screen refrigerators, washing machines, various smart kitchen products and smart devices, among others. Also announced were new scenario-based content offerings and partnerships to enhance user stickiness. The continued introduction of new and innovative products and partnerships is the best testament to our commitment to research and development, which will further strengthen our IoT product portfolio and differentiate our brand and products among peers. We have also been expanding our premium coKiing brand, which was first introduced in late 2019 with a series of AI-centric air conditioning products through increasing additional product categories across home scenarios. With the expansion of our premium coKiing brand, we will be offering a complete advanced and AI-centric product portfolio to the high-end market, further strengthening our brand image while diversifying our sales channels and consumer target markets -- consumer market targets to drive premiumization and deliver additional growth prospects. In terms of our overall marketing strategy, in addition to major product launch events and traditional advertising campaigns, we are diversifying our advertising and promotional channels in accordance with the latest consumer preferences and market trends. We continue our efforts to showcase our products through cooperations -- through cooperation with numerous KOLs on some platforms like self-media, Little Red Book, Douyin, TikTok, together with live streaming on e-commerce platforms such as Taobao and JD. We invite these KOLs to test and showcase our products as well as interact with their fans and consumers on these platforms. Such marketing strategies help us attract a wide audience of young consumers and increase their interest in the purchase of our products. In summary, looking ahead in 2020 and beyond, we will adhere to dynamic and prudent business practices, while maintaining stable expansion under our 5G + IoT strategic framework. We are fully committed to and confident in achieving our 3511 long-term objectives, our road map to becoming a large-scale, high-tech leader in the IoT @ Home space. That concludes our founder's comments. I will now provide a quick operational update and discuss our financial performance for the first quarter of 2020. Despite the adverse industry conditions in the first quarter, we achieved solid financial and operating performance. Net revenues recorded a double-digit increase, beating our previous guidance, thanks to our diversified business product and channel mix as well as our ever-increasing brand awareness across sales channels and among end consumers. We also continued to sustain a healthy level of profitability, having implemented a number of stringent cost control measures to offset the adverse industry-wide impact of COVID-19 while maintaining our commitment to research and development. The company's balance sheet remains strong with approximately RMB1.2 billion of cash and cash equivalents, short-term deposits and investments as of the end of the first quarter. The number of Viomi off-line experience stores is approximately 1,500 as of March 31 and has held relatively steady in the subsequent months. Our number of household users reached more than 3.7 million, and the percentage of household users with at least 2 of our connected products reached 18.4%. While uncertainties remain, we believe our financial strength and operational flexibility will position us well to capture the opportunities ahead as the industry and broader economy continue to recover. Let's now turn to detailed financial review of our first quarter results as well as the outlook for the second quarter. As Xiaoping discussed, net revenues were RMB765.5 million compared to RMB676.2 million for the first quarter of 2019, primarily due to the successful rollout and increased sales of certain Xiaomi-branded and Viomi-branded products, offsetting the broader industry-wide impact of COVID-19. Revenues from IoT-enabled smart home products increased by 8.0% to RMB542.7 million from RMB502.5 million for the first quarter of 2019, primarily due to the continued successful rollout of the company's smart kitchen and other smart products. Within this category, revenues from our water -- smart water purification systems decreased by 10% to RMB108 million from RMB120 million for the first quarter of 2019. The decline was mainly -- was primarily due to decreases in average selling prices despite double-digit year-on-year sales volume growth in the quarter. Revenues from smart kitchen and other smart products increased by 13.6% to RMB434.7 million from RMB382.5 million for the first quarter of 2019. The growth was primarily driven by the continued successful rollout of certain new products, in particular the Xiaomi-branded sweeper robot, which offset the broader industry-wide impacts of COVID-19. Revenues from consumable products increased by 35% to RMB65 million from RMB48.1 million for the first quarter of 2019, primarily due to increased demand for the company's water purifier filter products. Revenues from value-added businesses increased by 25.6% to RMB157.8 million from RMB125.6 million for the first quarter of 2019, primarily due to new product introductions together with increased demand for the company's small appliances products. Cost of revenues increased by 27.7% to RMB621.5 million from RMB486.8 million for the first quarter of 2019. Gross profit was RMB144 million compared to RMB189.4 million for the first quarter of 2019. Gross margin was 18.8%. The decline in gross margin as compared to the first quarter of 2019 was primarily due to the shifts in the company's product and business mix, together with decreases in average selling prices of certain product categories, including our smart water purification systems. Total operating expenses decreased by 12.4% to RMB134.2 million from RMB153.1 million for the first quarter of 2019, primarily due to our stringent expense control measures implemented during the quarter to offset the adverse industry-wide impacts of COVID-19, while continuing to invest in research and development. R&D expenses increased by 62% to RMB59.3 million, primarily due to increases in employee-related expenses, expenses associated with new product development and expenses related to the application of new patents. Selling and marketing expenses decreased by 35.1% to RMB65.5 million, primarily due to a decrease in logistics expenses as well as stringent expense control measures in relation to marketing and promotional activities and other selling and marketing-related expenses implemented during the quarter to offset the adverse industry-wide impact of COVID-19. G&A expenses decreased by 39.5% to RMB9.5 million compared to RMB15.6 million for the first quarter of 2019, primarily due to the company's stringent expense control measures. Net income was RMB17.8 million and non-GAAP net income, which excludes the impact of share-based compensation expenses, was RMB31.4 million. Now let's turn to our outlook. As discussed previously, while we have seen meaningful improvements as compared to the first quarter and the overall industry trend is encouraging, we believe our industry as well as the broader economy in China and globally are still facing significant challenges and uncertainties that will be difficult to quantify. In light of these factors, for the second quarter of 2020, the company currently expects net revenues to be between RMB1.25 billion and RMB1.28 billion, representing a year-over-year growth of approximately 7.7% to 10.3%. In terms of profitability, as a result of continued aggressive promotional campaigns, particularly with the upcoming 618 online shopping festival, together with ongoing destocking initiatives for previous generation products in preparation for the launch of several new product lines, we do expect gross margins to decline slightly in the second quarter as compared to the first quarter of 2020. Nevertheless, as a result of our stringent cost control measures, together with our dynamic and prudent business practices and execution capabilities, we do expect to continue to remain profitable in the second quarter, with a positive trend heading into the second half as such cost control measures take full effect and new higher-margin products contribute to a greater share of our overall sales revenues. The above outlook is based on current market conditions and reflects the company's current and preliminary estimates of market and operating conditions and customer demand, which are all subject to change. So this concludes our prepared remarks, and we will now open the call for Q&A. Operator, please go ahead.
