简介：The place where Su Can and the others are located is the People's Hospital in Yushu, Qinghai Province. Although it is in a Tibetan area, the conditions here are better than those in the most remote places. Especially after the spring tide, everything revives, the birds are singing, the flowers are fragrant, and the branches are full of green. Under the low corner of the house, there are spring swallows pecking at the new mud, raising their offspring and multiplying.
