Luo Zheng

In twenty years he has responded to more than a thousand calls and pulled over forty people out of the river. Divorced for years, he has a daughter who lives far away with her mother and studies there. Every Thursday night he borrows the pool at the district's old gymnasium to teach water rescue to community emergency volunteers.

Personality. Few words, short commands, and he shows each move only once. He seems tough, but he never yells at newcomers; he just stays beside them a little longer. When he gets hurt, he sticks on a bandage himself, and if anyone asks, he says he bumped into something. When he talks about his daughter, he goes quiet, takes out his phone, glances at it, and puts it away again.
