Thank you, Helen. Hello, everyone. In the second quarter of 2019 total revenues exceeded the high-end of our guidance driven by our robust growth of our mobile games and AI-related business. However, we must admit that our utility product business is still facing some challenges due to the misleading statements made by our third-party in later November 2018 which led to pause in some of our collaborations with business partners in overseas markets. While we have continued to talk with them to clear up this confusion, we have not yet being able to resume business -- business relations with some including Facebook. In the first half of 2019, revenues from utility products and related services decreased by 39% to RMB921 million. In the second half of 2019, we will continue to face the challenge of growing and suspending our utility product business revenues. On a year-over-year basis, the slowdown of our utility products and related services could decrease in our total revenues for the full-year of 2019. We will also continue investing in AI as our AI business still in its early stage of development. As a result, we could report operating loss for the full-year of 2019. Even though we’ve taken several steps to restart the growth of our business, some of the steps have already shown early upbeat results. First, our utility product and related service business continues to make healthy profit and cash flow in the first half of 2019. This business segment earned RMB244 million in operating profit. About RMB400 million MAU continue to be still be a strong source of revenues and a rich foundation for developing new products and service. Second, our mobile games. Mobile games business has continued to grow strongly and had become our growth engine for the company. In the first half of 2019, revenues from our mobile games business grew by 88% year-over-year to RMB591 million. We continue to see the growing user adoption of our mobile casual games in overseas market. According to third-party data, the overall mobile casual game market increased by 100% year-over-year in June 2019, driven by user growth in both developed countries and emerging market, such as India, Russia and Brazil. This rapid progress was also driven by gamers who had never played mobile games before joining our platform. The growing mobile casual game market had continued to put growth in our mobile game business. Cheetah Mobile continues to create hit games. Our games have been downloaded more than 2 million times in the past -- 2 billion times, sorry -- 2 billion times in the past years. Since 2019 we have launched seven games. Some of this games remains top casual games in overseas market and have been featured by either Google or App Store. For example, in late July we launched Beach Clean. Beach Clean is a light casual game that quickly became a top three app and a game on Google play in United states and a number of other developed country. We also continue to explore additional monetization opportunities through our current title by launching in game purchase items and in game rewards. These have helped us to continue growing app -- growing our app. Importantly, our flagship games, including Piano Tiles 2, Rolling Sky, Dancing Line, and Bricks n Balls continue to do quite well and have begun to form a portfolio of well known mobile game IP. In the second quarter of 2019, our flagship game operating margin expanded to 28% from 23% in the same period last year due to better operating leverage. Third, despite the early stage of development, we’ve already launched several popular AI-based products together with Beijing OrionStar. We are also a single largest shareholder of Beijing OrionStar. We believe that development of 5G technology will create opportunity to grow the number of voice and visual interactive product and solution on to the market quickly. Our voice and visual interactive product offering have been used in many place, such as convenience stores, office buildings, KTVs, shopping malls, hotels, after school classes -- class and more. In the first half of 2019, our AI and other revenue increased to RMB80 million from RMB22 million in the same period last year. In the future we will be able to enhance the monetization strength of our AI-related business as user adoption for our service continues to grow. With this in mind, we will continue to invest in and focus on AI to resume our growth. Lastly, I would like to finish my speech today by announcing our Board -- that our Board has declared a cash dividend in the amount of US$0.5 per ADS which will amount to a total cash payment of about US$72 million. Our special cash dividend payment demonstrate our commitment to delivering shareholder value, which we are facing some difficulty. We are confident in our company's long-term potential. We believe that our legacy mobile internet business which include our utility product business, mobile game business and LiveMe will resume to growth in the long run and will remain profitable. In addition, we are excited about some of the new prospects of building a new growth engine around the AI to enterprise service and we’re confident in our long-term return in the AI investment. Despite that our AI business is still in its early stage of development, we’ve sufficient cash to be able to fund this new business. We have also made some good progress in building sustainable business model for the AI business and we hope to see meaningful return on the investment soon. With that, we will now turn the call to our CFO, Vincent Jiang, to go through the details of our second quarter financial results.
