This guy flew to China on Jan 1 2022, tested positive, spent 3 months in quarantine hotels, and then flew back to the US on April 1st 2022.

Some quotes (translated):
From the first quarantine place where he is in the same room as other people: There is no medical treatment. We don't have any symptoms, so we just wait for the virus in our body to slowly go away as a natural process.
Near the end: The situation is the same as described in the recent recording on the Internet: the health cloud app says negative. The CDC says you are positive, but they don't give you a notification. They just say that there is a problem and you need to go to a hospital and can't be let out of quarantine.
