A person in the Song

“We couldn't determine the origin. Last night, a heavy rain suddenly appeared in the back garden. In my belongings, I found a strange object with this person's portrait on it, claiming to be Zhao Jun, born on February 15, 2000. The back also wrote "People's Republic of China Resident Identity Card...",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...,Zhao Jun was still terrified, muttering to himself: "I believe in traditional Chinese medicine, I believe in traditional Chinese medicine... But for this illness, we should go down the mountain to a big hospital. Even if it doesn't help, we should at least get a CT scan."。
