Thank you, Wang. Robust revenue growth momentum continued in the second quarter, increasing 36.6% year-over-year, as the company benefitted from strong global unit sales, particularly with the newly launched Mi-Band 4. During the quarter, we shipped 8.3 million total units, up 53.7% from the same period last year. We believe this topline growth momentum is sustainable and has the potential to continue improving. In addition to the products which we already launched earlier this year, we will soon launch more Amazfit new products with various functionalities in the next quarters. These new product releases demonstrate Huami’s commitment to the needs of global smart wearable consumers and give us the confidence to continue delivering value to our shareholders in the second half of 2019, as Wang mentioned earlier. We will continue to benefit from our expanding overall brand recognition as we enhance our products and services, and continue to penetrate global markets. Also during the second quarter, we continued to make strategic investments in our R&D capabilities, including strengthening our algorithm and cloud services capabilities, in addition to streamlining product development, testing and supply chain management for new launches, all in an effort to ensure we remain on the cutting edge of smart wearable technology. We also continued to make investments to our brand value, by increasing our marketing efforts to promote broader awareness and adoption of our self-branded products. We are confident these investments, along with strong alliances, operational efficiency and a growing global footprint, will help ensure our healthy growth and solid financial performance in both the short- and long-term. Mindful of the length of this call, I will highlight the key financial measures for the second quarter 2019 and encourage you to refer to our earnings press release for further details regarding our financial results. Now, here are some of the highlights of our strong second quarter. Revenues increased by 36.6% to RMB1.04 billion from RMB760.1 million for the second quarter of 2018, exceeding the guidance we provided to the market. Gross profit increased significantly by 40.8% to RMB277.3 million from RMB196.9 million for the second quarter of 2018. Our gross margin of 26.7% reflected a sizeable improvement from our gross margin of 25.9% for the second quarter of 2018. The increase, aside from economies of scale, was driven by our continued improvement in supply chain management. Strong supply chain management has always been a hallmark of our operations and we are continually working to find ways to make it even better. In 2018, we consolidated and streamlined our logistics and supply network activities by establishing a dedicated supply chain management global headquarter in Shenzhen. Here, all relevant teams are under one roof. The ease and speed of communication among teams and with the suppliers and manufacture contractors has further improved our operational efficiency. Now, moving on to expenses. Total operating expenses increased by 89.2% to RMB185.2 million from RMB97.9 million for the second quarter of 2018, reflecting our investment strategy in R&D, branding and marketing channels for long-term returns. Research and development expenses increased by 111.4% to RMB93.8 million from RMB44.4 million for the second quarter of 2018, primarily due to an increase in personnel-related expenses and a rise in intermediate test expenses as several new pipeline products were undergoing rigorous testing. General and administrative expenses increased to RMB51.0 million from RMB32.8 million for the second quarter of 2018. This increase is in line with the growth of the company. As our total revenues and volume of products sold have continued to increase, our selling and marketing expenses have naturally also increased. Selling and marketing expenses increased by 95.2% to RMB40.4 million from RMB20.7 million for the second quarter of 2018, as we intensified our promotion efforts for self-branded products. We also expanded our sales and marketing team to boost our sales efforts globally. Our income before income tax was RMB101.3 million, compared with RMB101.4 million for the second quarter of 2018. The GAAP Net income attributable to the company increased to RMB89.4 million, compared with RMB85.5 million for the second quarter of 2018. Net income attributable to ordinary shareholders of the company increased to RMB89.2 million. Moving down the P&L. Basic and diluted net income per ADS attributable to ordinary shareholders of Huami Corporation was RMB1.46 and RMB1.39, respectively. As a reminder, each ADS represents four Class A ordinary shares. Next, Adjusted net income attributable to Huami Corporation increased to RMB111.7 million from RMB101.6 million for Q2 2018. Finally, adjusted basic and diluted net income per ADS attributable to ordinary shareholders of Huami Corporation was RMB1.83 and RMB1.73, respectively. Relating to cash, as of June 30, 2019, the company had cash and cash equivalents of RMB1.45 billion, compared with RMB1.44 billion as of December 31, 2018. And now to our outlook, looking ahead to the third quarter of 2019, management currently expects net revenues to be between RMB1.64 billion and RMB1.67 billion, which would represent an increase of approximately 52.6% to 55.4% from RMB1.07 billion for the third quarter of 2018. This concludes our prepared remarks. We will now open the call to questions. Operator, please go ahead.
