Cai Mingjing is a fourth-grade Chinese teacher at Yangshan Road Primary School in Danjiangkou City, Hubei Province. For 4 years, she has taken rural children to write poems and paintings in nature, "seeing" colorful childhood and the wider world.

She is more afraid of "doing nothing" than the difficult conditions at the teaching point. Cai Ming Jing has helped every child put on a quilt, cut his nails and washed his hair. On the way to the home, several boys rushed over and said: "Sister Cai, I saw the dog from a distance"
