Thank you for having such people in Shanghai who dare to tell the truth, real Shanghai people. There are many such people in Shanghai.
Probably the content is this:
Disease control, health cloud, and medical institutions are now all separate and chaotic;
The elderly at home should try not to go to the Fangcang shelter hospital, just stay at home for observation, and rest for three to five days asymptomatic;
If 120 comes to pull the elderly into compulsory isolation and ask them to show the certificate of the elderly's "positive", there is a high probability that they will not be able to show it...
Regarding "useful knowledge", it is actually "asymptomatic and mild". Home isolation is a better choice, because this disease does not require special treatment, and can be overcome like a cold.
If they all get to the Fangcang shelter hospital, the conditions are very poor, and there will be no treatment, but it is not conducive to the recovery of the patient.
