Hello, everyone. First, I would like to report our first quarter performance in 2022. Our revenue reached $55.3 million in the first quarter, exceeding the high end of our previous guidance range. Revenue represented a year-over-year decrease of 2.7% compared to the quarter of 2021, where we saw rapid growth across the industry. Our IoT PaaS business revenue decreased year-over-year to $41.8 million in the first quarter. Consumer discretionary spending was adversely impacted by high inflation and the Russian, Ukrainian conflict that started in the first quarter further exacerbated global inflation. In this environment, we observed that IoT brands have become more conservative. On the other hand, our 2B-based SaaS and other segments maintained a strong growth momentum for the fifth consecutive quarter with revenue reaching $5.8 million, representing a year-over-year increase of 146.7%. This performance was driven by our consistent effort to offer target solutions to address the critical issues of our enterprise customers by leveraging our strong product functions and the Tuya device ecosystem. In addition, since our smart private cloud product, Cube Solution was launched in the last November and officially released in early this year. It has achieved important breakthroughs with new customers in the first half of this year. On the customer front, as we continued to iterate our products and services, our total number of customers increased by 29% from the same period last year to approximately 3,900 in the first quarter. IoT PaaS premium customers with revenue contributions of more than $100,000 during the past 12 months increased from 216 as of March 2021 to 303 as of March 2022. Our ability to maintain a large-scale customer base enabled us to leverage our platforms, economies of scale and improve the network effects between our business as well as our customers. In addition, the diversity of customers also helps reduce external risks in an increasingly uncertain macro environment. While some downstream brands are slowing down their sales and production plans, others are increasing their purchases. For example, the deployments of an established Canadian smart home brand with business across over 100 countries and regions, reaching the millions in the first quarter, 6x more than what they ordered in the same period of last year. Moving to gross profit margin. In the first quarter, both our overall gross profit margin and IoT PaaS gross margin improved slightly year-over-year to 41.2% and 42.3%, respectively, remaining relatively steady compared to the same period of last year and the previous quarter. Now let me share the specific progress of our business in the first quarter. During the past 12 months that ended March 31, 2022, the dollar-based net expansion rate of our IoT PaaS business segment was 122%, remaining at the top of the cloud path and the SaaS industry. We garnered nearly 500 new customers on our IoT PaaS business, growing the total number of our IoT PaaS customers by 21% year-over-year. In this Q1, we continue to attract and acquire reputable new companies across the globe as customers of our IoT PaaS business through our Tuya Plus Strategy. In Europe, for example, we officially started a partnership with a German supermarket giant with business worldwide. That has been one of the Fortune Global 500 for many years. We collaborated with the self-operated brand in the electrician lighting field. Another customer is a leading Dutch brand, Smartwares, with products sold all over the world. This Dutch customer entirely shifted from its own IoT platform to the Tuya platform, which will enable them to achieve breakthroughs in all their product categories, starting from home appliances and sensors. In the Czech Republic, EMOS, a dominant local tools and hardware brand also started a partnership with us and now have more than 30 SKUs in the pipeline already. In Asia, we enabled Korea's top 3 smart home brand listed company, Kocom, to implement visual capabilities into installed bell products. We also launched joint efforts with one of Japan's leading furniture retailer and the listed company to explore new business opportunities in the field of home appliances. We are also in the process of helping India's well-known emerging consumer electronics brand boAt to expand into TWS Bluetooth handsets and IoT consumer electronics products, including smart glasses in the future. Given the current macro environment, like smart Bluetooth products will be the key strategic focus in 2022. In South Africa and other regions, notable new customers included [Macroled], a leading brand in Argentina that focuses on offline product distribution and has more than 1,000 partners covering the entire South America continent. Macroled became a strategic customer of the Tuya's Star Volunteer program. In North America, a listed company and the market leader in the R&D and the production of RVs, pickup trucks, yards and spare parts confirmed their partnership with us in the first quarter to build a smart RV ecosystem. We now also further expanded our customer base in North America with a leading audio and video solutions and [accessories] brand, a leading residential irrigation equipment brand, a leading environmental appliances, health and personal care brand and many others. This new customers' business both covering from personal entertainment to environments, outdoor and others. Domestically, the resurgence of COVID after holiday season in the second half of the first quarter substantially limited our business activities in China. However, our outdoor business line, which has been one of our key product categories, still acquired multiple customers with immense business potential. These customers included leading the eco information system developed and the undisputed leader of the domestic [Indiscernible], and the leader in the portable and home energy storage industry. In addition, we launched the 100 Days for 100 Brands plan to penetrate Chinese e-commerce [LC] brands before the spring festival this year and successfully acquired more than 100 target customers by the end of April. The addition of this new customers from all over the world further boosted our core customer base. The breadth and the expertise of their products and services also serve to illustrate strong competitiveness of our platform in the global intellectualization market. The quality of our customer base will enable us to strengthen the core of our business during this downturn for smart consumer electronics. The foundation we have set fuse us with hope and excitement for the opportunities that will come when the industry eventually recovers. In the first quarter, we continue to diversify our business and our IoT PaaS product categories are increasingly balanced. In terms of contribution, electric lighting accounted for about 40%. Consumer IPC and census accounted for about 25%. Household appliances, kitchen appliances, pets and other small appliances accounted for about 20%. And other emerging categories accounted for more than 15%. Among them, the electrical and lighting categories, which constitute a significant portion of our revenue, has been largely affected by inflation, recording a year-over-year decrease. This decrease was mainly because consumer-grade electrical and lighting products are price-sensitive products, usually sold in large quantities. Smart products typically sell for approximately 3x the price of traditional products. As a result, consumers tend to shift their purchasing needs to conventional products and will sacrifice smart functions or delay the purchase of smart products to save money. This market shift was especially notable in Europe and America. In other categories, we observed that the smart IPC and security sensor products, which have relatively high IoT penetration rates, are in strong demand. This is driven by the unique characteristics consumer IPC and sensor products where IoT functions are necessary to maximize security. Meanwhile, household appliances with little price gap between IoT and traditional products maintained a solid year-over-year growth momentum. Next, I will share some updates on our sales and other segments. This segment continued its robust performance in the first quarter with revenue increasing 147% year-over-year to $5.8 million. First, in commercial lighting, our premium SaaS solutions were adopted by China Construction Development Corporation, which has been ranked among the Fortune Global 500 for 5 consecutive years for its street lighting project in Xiamen. Mexican industrial lighting brand, Dimas Lighting also leveraged our software capabilities to complete construction of its intelligent platform for commercial lighting and implemented several industrial lighting projects. Our top 3 lighting brands in the world also expanded our partnership into its sliding business in its Korea business segment. The customer utilized our commercial lighting SaaS solution to improve its smart lighting capabilities and will leverage smart lighting products developed on the Tuya platform. This is a prime example of how our SaaS and PaaS business complement each other in our ecosystem. Turning to the progress of our hotel and apartment subsector, we recently launched a strategic partnership with Alipay in China. Internationally, the leading hotel system integrator in Malaysia, Core System Technologies, is using Tuya's hotel SaaS solution to land at the first smart hotel in Malaysia. Additionally, the smart products arm of a world famous Fortune 500 group is cooperating with us to use our hotel rental SaaS and platform SDK capabilities for overseas hotel rental operations. As the pandemic is being brought under control in Q2, our hotel SaaS solution has received a number of orders from Europe and Southeast Asia. For value-added services, the strong momentum of our customer paid tariff services carried through into the first quarter with revenue broadening over to 100% year-over-year. The number of active devices with paid cloud storage service by the end of the first quarter of 2022 also doubled from the same time last year. Finally, let's talk about this year's core strategy, our smart private cloud product, Cube Solution. In the first half of 2022, we have made substantial progress in our private cloud business. After thorough evaluation and license and inspection, several leading customers in different countries and industries have recognized our private cloud solution. For example, Telkom Indonesia, the largest telecom operator in Indonesia with service coverage of over 55% of all Indonesia household and hundreds of millions of registered users will use our Cube Solution to tap into the strong consumer spending power of consumers in its network to accelerate the development of its Indonesia smart home appliances market. Our goal in such collaboration is to become its long-term partner in 3 ways: first, private cloud platform software development; second, powered by Tuya ecological smart devices interconnections; and finally, additional recurring value-added services for the end users. In China, a China leading utility giant is establishing the long-term collaboration agreement with Tuya to build its own IoT intelligent platform in stages. Our Cube Solution will help customers complete their deployment of IoT private cloud platforms and build their IoT platform capabilities. Cube can also support customers with security software capabilities to help adjust the energy consumption security issues for thousands of households. These qualities also helped us to attract industry leaders such as 1 of the China's top 5 2-wheel and 3-wheel electric vehicles develop [Indiscernible] Cube Solution. So far, we are getting positive feedback from our customers that they choose our products and trust us because of our product innovation of technology covering cloud edge and application and the scale effect of the integrated software and hardware products based on our deep cultivation in the intellectualization field for more than 7 years. As well as our reach powered by Tuya device ecology through a long-term accumulation in the years, we believe in our ability to capture long-term opportunities in the market with strong demand for smart private cloud solutions. Overall, the first quarter is full of challenges, economic and other disruptions that started in second part of the 2021, intensified in the first quarter, aided by the Ukraine war. Global inflation is running high and is not expected to improve in the second quarter. While we remain cognizant of these major challenges in our IoT PaaS business, we will explore additional growth drivers through our smart private cloud and smart industrial SaaS segment. On profitability, in this quarter we focused on the optimization of our organizational structure efficiency as we aim to better balance our business growth and time line to profitability. And we're also improving our management efficiency simultaneously, which will sustain our long-term prospects. That concludes my remarks. I will now turn the call over to Jessie, our CFO, to review the financials.
