Good morning and good evening, everyone. Welcome and thank you for joining our fourth quarter and the full year 2019 earnings conference call. In the fourth quarter of 2019, we delivered strong financial results and solid operating performance. Our customer metrics continued to show strength. During the quarter, total active customers grew nicely at 19% year-over-year. The number of active customers for the full year of 2019 increased by 14% year-over-year, reaching RMB69 million. These are the results of solid customer retentions and improved customer stickiness. In 2019, repeat customers as a percentage of total active customers increased to 80% from 76% in 2018. We were able to achieve this success due to our focus on discount apparel. In the fourth quarter of 2019, apparel-related categories contributed to -- over 70% of our total GMV. Since the fourth quarter of 2018, we have spent a lot of time and effort in improving our merchandising, offering desirable product to our customers at a deep discount. This has paid dividend to our business in 2019. Going forward, we remain committed to the execution of our merchandising strategy, further enhancing our product offerings. In November 2019, we discontinued our delivery unit operated by Pinjun and begin to work with SF Express. As a result, our delivery service has improved and our delivery cost has come down, allowing us to reinvest in enhancing the overall customer experience on our platform. For example, in December 29, we lowered our free shipping threshold from RMB288 to RMB88, and the returns are now free. We also upgraded the benefits for our Super VIPs. On top of existing benefits, they now receive additional 2% off. We believe these changes will encourage customers to shop with us more, further enhancing our customer stickiness. Currently, we are experiencing some short-term impacts from the novel coronavirus outbreak, which has affected our sales in the first quarter of 2020. The apparel category was especially impacted as customers are not leaving their home as much, which decreased their demand for apparel. We are working closely with our suppliers to get through this difficult time together. The good news is, we have seen some signs of recovery in March and believe customers demand will rebound quickly once the virus is contained. We continue to have full confidence in the strength of Chinese economy and the long-term growth potential in China's discount retail market. At this point, let me hand over the call to our CFO, Donghao Yang, so that he may discuss our strategy in more detail, and go over our operational and the financial results.
