In desperation, the peony parrot hit the wall. What should I do? ! !

Block it with your own body and see if there is anything special on the wall. If you can, get some smoke anesthetic to stun it and see if there are any unknown protrusions on it, which may be parasites! If you can't come back, you will linger on, and cutting it off with a knife for the first time will not bring it pain and sorrow. You can't let the nearby death torture it (children and women can't be there), and then bury the body or burn it to prevent the virus from spreading.
