Leaders have sent their own anti-epidemic video comments. I hope that the epidemic will pass as soon as possible and everyone will be safe and healthy. Countless people watch day and night, and countless people are accompanied by each other. The retrograde rescue of countless people has lit up the hope of doctors and epidemics, wings and epidemics, friendship and epidemics in countless people's hearts. Winter is no longer cold, and victory is no longer far away. Pay tribute to those who are retrograde.
