Thanks, operator. Good morning and good evening to everyone on the call. Welcome to Aurora Mobile's third quarter 2020 earnings call. Before I proceed, I would like to take this opportunity to remind everyone that we have uploaded the quarterly earnings deck on our IR webpage for your reference. You may refer to the deck as we proceed with the call today as it contains useful financial information in addition to those we have in the press release. Let's begin our review with highlights of our key operating and financial performance for the third quarter of 2020. First, the number of mobile apps utilizing at least one of our developer services or the cumulative app installations reached 1.65 million as of September 30, 2020 from approximately 1.39 million a year ago, an average of 12.7000 new apps came on board every month during the third quarter. Quarter-over-quarter, we still see the great number of mobile app developers joining us and we are truly humbled yet encouraged by this trend. Second, the number of monthly active unique mobile devices we cover continued to increase reaching 1.39 billion in September 2020 from 1.34 billion in September 2019. Lastly, in the third quarter of 2020, we saw the number of paying customers increased to 2,405 from 2,312 a year ago. On-to the Q3 2020 financial numbers, please refer to our presentation deck uploaded to our IR webpage for the key financial highlights. I would like to begin with the discussion of SAAS Business, which includes only the Developer Services and Vertical Applications business, because it's appropriate, relevant and helpful for investors to understand how the underlying SAAS Business are performing now. At beginning with the quarter ending March 31, 2021, we will only have this SAAS Business. Our SAAS Business continue to record impressive result in this quarter with revenue of RMB65.6 million, or 18% growth year-over-year and gross profit of RMB49 million, or 16% growth year-over-year. On a SAAS Business basis, the total revenue grew 18% year-over-year, mainly due to the strong 99% growth in Developer Services, partially offset by the decline in vertical applications, which have been impacted by COVID-19. It's worth noting that customer demand for Vertical Applications have gradually recovered from the second quarter of this year and revenues from Vertical Applications have been sequential growth for two consecutive quarters. On a quarter-over-quarter basis, revenue remained relatively stable at RMB66 million. On a SAAS Business basis, gross profit has also shown solid growth of 16% year-over-year to RMB49 million for the quarter ended September 30, 2020, due to the same reasons as what happened to the revenue trend. Also on a SAAS Business basis, gross margin for this quarter was 75% stable year-over-year and quarter-over-quarter. We expect pro forma gross margin to maintain at about 60% range going forward. In the third quarter, we continued to extensively explore various industry verticals, focusing on helping mobile app developers with operations, growth and monetization by leveraging our professional, efficient, secure and stable services and great operational analysis capabilities. During the quarter, we launched a one-stop operational platform for app developers, helping them to improve user engagement, retention, and conversion, as well as achieve greater efficiency, leverage on intelligent user acquisition tools to further refine their operations. Recently, we also signed strategic cooperation agreements with leading platforms across a greater variety of industry verticals, such as finance, insurance, weather, Internet tools, gaming, fresh food e-commerce, and online education to drive user growth and traffic and improve user experience. For example, we have already signed agreements with Ping An Bank, Data Center of China Life, Moji Weather, WiFi Masterkey, Lilith Games, Missfresh, and 17zuoye, and other well-known companies. Now, I'll turn the over to Fei, who will discuss the Q3 performance in great detail.
