I received the message from Yuhang, Hangzhou. Did you change the code?

Not if you are far away. Report to the community in time and do nucleic acid as soon as possible.

As soon as possible, carry out the nucleic acid test nearby (if residents have touched the bag, they will also do the nucleic acid test together), and there are no other control requirements for the time being. If you still leave the courier box and courier bag at home, treat them with chlorine-containing disinfectant, and let the unopened package stand for 7 days before unpacking. In the near future, it is suggested to minimize mail order and express delivery items from countries and regions with high risk of overseas epidemics. If you really need to buy, you should do a good job of personal protection when signing for the express mail and unpacking it.
