A person in the Song

There's a teaching volunteer acceptance letter, along with a teaching training certificate, a student ID card from Renmin University of China, and some clothing. There's also a small metal box and a large one, a bunch of bottles and cans, some black and white thread, and some other books...,After thinking for a moment, Yan Shu asked, "How is that person doing",“That's easy. I think when he wakes up, we can go see him, observe his words and actions, speak as little as possible, and listen as much as we can.”。
