Thank you, Xinxin. Good morning or good evening to everyone. Let's move on to our operational and financial review for the first quarter of 2021. As shown on Slide 19, our hotel rooms expanded by 15% in Q1 2021 to 662,000 compared to 575,000 in Q1 2020. Excluding DH, legacy Huazhu hotels room expanded by 18% year-over-year to roughly 638,000 in Q1 2021. While hotel turnover in Q1 2021, despite COVID-19's resurgence impacts in China and prolonged lockdown in Europe, our total hotel turnover still grow at a 66% year-on-year to RMB 8.2 billion in Q1 '21. This is mainly due to our continuous network expansion as well as the low base for Chinese business last year, but unfortunately offset by the high base of DH last year. Excluding DH, legacy Huazhu hotels turnover doubled year-on-year to RMB 7.9 billion in Q1 2021 and recorded a 10% increase if compared to Q1 2019. Turning to Page 20. Legacy Huazhu's blended RevPAR for Q1 is RMB 138, which has recovered to 77% of 2019 level. The ADR in Q1 2021 has recovered to 95% of 2019 level to RMB 209, while occupancy in Q1 is 15 percentage points lower compared to 2019. This was mainly due to the COVID-19's resurgence and the stay-local policy in January and February. However, our RevPAR started recovering strongly since late March. Turning to Page 21. Our legacy DH business has been negatively impacted by the second and third wave of pandemic since September 2020. German government imposed a lockdown from last November, and it may extend to early June this year. Therefore, our legacy DH-blended RevPAR for Q1 2021 declined by more than 70% to EUR 13 compared to 2021 Q1. The ADR dropped by 23% to EUR 69, and the occupancy dropped by 33 percentage points compared to 2020 Q1. On Slide 22, the total net revenue grew by 16% year-on-year to RMB 2.3 billion in Q1 2021. Excluding DH, legacy Huazhu recorded a 69 percentage year-on-year growth rate to RMB 2.2 billion. The revenue growth was better than our previous guidance, thanks to the strong recovery in late March. Breaking down the revenue of Q1, leased and owned revenue decreased by 8% year-on-year to RMB 1.4 billion mainly caused by the decrease of leased hotels in Europe. Excluding DH, leased and owned revenue of legacy Huazhu grew by 56% year-on-year to RMB 1.3 billion. Net revenue from manachised and franchised hotels grew by 93% to RMB 897 million, mainly driven by year-on-year growth rate of legacy Huazhu. Due to the significant drop of leased and owned revenue of DH in Q1 2021, manachised and franchise revenue contribution enlarged to 39% in Q1 2021 compared to 23% in Q1 last year at a group level. For legacy Huazhu, as our hotel expansion was mainly through asset-light model, the revenue contribution from manachised and franchised model also expanded to 41% compared with 35% a year ago. Now let's move to the cost and profitability session on Slide 23. In Q1 2021, the reported operating loss was RMB 575 million, narrowed from RMB 857 million in Q1 2020, but expanded from a quarter ago because mainly due to the COVID-19 resurgence and the state and local guidance in China and also prolonged lockdown in Europe. Excluding DH, legacy Huazhu's operating loss in Q1 was RMB 172 million, narrowed by RMB 560 million compared to the loss of RMB 731 million in Q1 2020. The hotel operating costs and other operating costs for Q1 2021 was RMB 2.5 billion, a slight increase compared with last year in which legacy Huazhu recorded RMB 2 billion hotel operating costs, indicating a 21% year-on-year growth. The increase was mainly attributable to the higher rental cost of the new upscale hotels, higher personnel costs as we keep growing the hotel network rapidly and higher depreciation and amortization costs, which were related to the upscale hotel openings and upgrading of existing hotels. As we mentioned in previous quarters, our future expansion of upscale hotel will mainly use asset-light model. Therefore, opening costs declined by 81% year-on-year and 40% Q-on-Q to only RMB 21 million in Q1 2021. Our SG&A in Q1 2021 increased by 9% year-on-year to RMB 406 million, mainly driven by the increase of legacy Huazhu but offset by cost savings of DH. Excluding DH, SG&A for legacy Huazhu increased by 31% year-over-year to RMB 299 million. The increase was mainly attributable to the increase of selling and marketing expenses related to revenue recovery and also the increase of head count for our BD team to support penetration into lower-tier cities and also affected by less government subsidies booked in the Q1 2021 compared to Q1 2020. Turn to Page 24. Our adjusted EBITDA loss narrowed to RMB 133 million compared to RMB 704 million a year ago. DH was the main drag for this quarter. Excluding DH, legacy Huazhu would have recorded a positive adjusted EBITDA of RMB 207 million compared to a loss of RMB 631 million in Q1 2020. In this quarter -- in Q1 2021, we recorded adjusted net loss of RMB 451 million narrowed from RMB 1.1 billion a year ago. Excluding DH, legacy Huazhu recorded an adjusted net loss of RMB 150 million compared with RMB 981 million loss in Q1 2020. The non-GAAP pro forma adjustment mentioned on this page exclude unrealized gains or losses from fair value change of equity related to some of our investments. For example, in Q1, we recorded RMB 238 million fair value increase of Accor shares we hold. Coming to the cash position. We kept the net debt of RMB 5.2 billion by the end of Q1, and there's no risk of breaching the financial covenants of the USD 1 billion syndication loan. Our cash balance was RMB 5.7 billion, and the unutilized bank facilities were 6.5 billion. These cash and bank facilities will allow for Huazhu to further pay down the existing bank debt in 2021 and also to be used for any unforeseen circumstances. As mentioned in previous presentations, the lockdown in Germany has greatly affected DH business. Therefore, the average occupancy of DH in Q1 was 19%, and the rate further dropped to 15% in April and May. Having said that, daily newly diagnosed figures in Germany are decreasing steadily. As of May 22, about 40% of Germans had received at least one shot of vaccine. In several regions like Berlin, the travel restrictions are partially lifted, and we expect to see more travel for the vaccinated people in June. To compensate the business loss, the German government has extended the scope and duration of government subsidies, including short-time worker compensation and extra government subsidies. As of April 2021, DH has received EUR 12.7 million short-time worker compensation, which is expected to further increase as the lockdown extend. Additionally, DH has applied for government subsidy to compensate the loss both in 2020 and 2021. The prolonged lockdown will certainly impose pressure on DH's revenue, but the impact will be partially offset by the government subsidies at EBITDA level. We will only record that income upon the recipient of the formal confirmation of such cash. We also continue to negotiate for rental deduction. Compared with EUR 5.4 million waiver achieved in 2020, the year-to-date waiver of 2021 has amounted to EUR 4.2 million. We continue to work on rental reduction through the years. The number quoted here are related to cash savings, but the P&L impact actually varies depending on the term of waiver. In addition, we have also put our staff on temporary furlough, frozen our head count and reduced discretionary spending and also CapEx. We are also in discussion with local banks in Germany for additional coronavirus age loans. The banks have been supportive to us. Turning to Page 28 for guidance. For the second quarter of 2021, we now expect the total revenue to grow by 87% to 89% compared to second quarter of 2020. Excluding DH, we expect the revenue to grow by 90% to 92%. To provide a more meaningful guidance, we expect the total revenue to grow by 27% to 29% if compared to the same period of 2019. Excluding DH, the 2021 revenue is expected to grow by 20% to 22%. For the full year of 2021, COVID-19's resurgence in January and February slowed down our hotel open plan in the first quarter. Also, echoing Jin Hui's point previously, we put more emphasis on quality hotels expansion. We now plan to revise down our nonstandardized hotel brand opening for the full year. Considering the above 2 factors, we lowered our gross opening target of 2021 from 1,800 to 2,000 hotels to 1,600 to 1,800 hotels. However, even with the slight downward adjustment of gross opening, our revenue guidance for legacy Huazhu remains unchanged at 50% to 54% growth compared to 2020 or 15% to 19% growth compared to 2019 due to the better-than-expected RevPAR recovery and the limited time impact of the hotel openings in the later part of the year. The prolonged lockdown period in Germany has caused the recovery much slower than previously expected. Therefore, we adjust down the full year group revenue growth guidance to be in the range of 44% to 48% compared to 2020 or 31% to 35% growth compared to 2019 from previous guidance of 50% to 54% growth compared to 2020 and 36% to 40% growth compared to 2019. With that, let's open up for Q&A. Thank you.
