As the old saying goes, heroes have been teenagers since ancient times. Young people are full of high spirits and have deep-rooted ambitions and heroism. In front of me is a thousands of feet sunshine, and in my heart is a loyal sky. Energetic young people often write heroic epics.

In Shimian County, Ya 'an City, Sichuan Province, there is a square once named after a teenager-Laining Square. It carries the local people's deep memory of this boy. The so-called ambition is not high, and the story of this young hero who put out the fire was once written into a textbook for future generations to learn.

But with the passage of time, the story of this young hero gradually disappeared from the book ... such a young model who was once called "North Lei Feng, South Lai Ning" with Lei Feng.

Shimian County, Lai Ning's hometown, is built on the mountain, which is a famous local fire danger zone. In the 1970s, Shimian County's economy was still underdeveloped, and every household was used to burning firewood or straw for cooking. Occasionally, in a small village built on the mountain, leaving sparks in the forest on the roadside will cause mountain fires. On the way to school and home in Laining, there are bound to be mountain roads. So whenever Lai Ning sees some small fires, he will take the initiative to put them out. In Lai Ning's mind, this is a good thing to contribute to the collective, and he put the sense of social responsibility in his heart early.
