1940, Hua Guan left home for the anti-Japanese battlefield and fought in the north and south for many years. He witnessed the head of the children's league in his village, leading a group of innocent children to stand guard, sending a chicken feather letter to the Eighth Route Army and climbing trees to catch the enemy.

After joining the army, childhood scenes always come to mind like movies. In this way, "Little Hero Rain Comes" takes rain as the protagonist, which became the beginning of Hua Guan's creative career.

The work "Rain Not Dead" was published in 1948 People's Daily, the former Shanxi-Chaji Daily, and was well received by readers as soon as it was published. In the early days of the People's Republic of China, an editor in charge of Chinese textbooks from the Ministry of Education made a special trip to find Hua Guan and told him that Xiao Jieyu was selected as a national Chinese textbook. Since then, the little hero Yu Lai has become a hero of a whole era in the eyes of children all over the country.
