Xxx male (female) was born in XXX, whether in party member or not, the spring is chilly. When the comrade passed the Chushu Bridge on the east bank of the canal, he found an old man falling into the water, struggling desperately in the water and gradually sliding towards the middle of the river. Facing the danger, he jumped into the unknown deep and cold water and swam to the drowning man with great effort. After some efforts, even the test of life and death, the old man who fell into the water finally saved the day with his faith when his physical strength was almost exhausted. In the face of the rescued old man asking his name, he only answered with "small things, small things", turning a bleeding foot pierced by rubble in the water and fading out of everyone's field of vision. After half a year's probing, the old man in Wang Qinghua finally got the name of Cai Zhisheng from a fisherman. Newspapers, radio newspapers and radio stations also reported that he saved people without leaving a name. What he did warmed the family and society in Wang Qinghua.
