I really doubt this whole thing about finding PCR positivity on the package's exterior being a source of import into the country? Especially if it's on the exterior of the packages.
A year ago, frozen food were detected as PCR positive and cause dozens of local citizens were infected in Dalian and this happened several months ago again. 5 months ago, a flight from India caused some Nanjing local citizens infected and it spreaded to several cities and this happened this month in Xi'an again. Now, Xi'an is locked down like Wuhan and the virus is still spreading. This winter could be a long hard one. As the Winter Olympic Games is about to open, we don't have any time to waste. But right now, someone still want to escape, this may cause more and more people infected.
Sometimes, we always ask ourselves. Is that freedom very important? What happened if we are sick? Got infected and isolated in hospital is just like in prison. You know, in our country, even your family member is in hospital, no matter what kind of sickness he/she got, visiting is prohibited. If he/she needs nursing, only one family member could stay with him/her. But this member need to have a PCR check as negative and report is in 72 hours, after 72 hours, he/she need to check again.
Well, my wife is in hospital right now. What I could do is only to give her any supply she needs. Even I have PCR check, I can't enter the ward, I could only bring the package to nurse station. Those who has not PCR check records in 72 hours even can't enter the building.
That damned COVID-19 virus. We are enough for this. I just wonder how soon could we stop it?
