Extended data:

Sanmao Joining the Army tells the story of 1937. The Japanese invaders brazenly launched a full-scale war of aggression against China, and the homeless Sanmao joined the army. San Mao stood solemnly in the queue, dressed in a totally unsuitable plus-size military uniform, and took part in the recruit training. However, in the Grenade live-fire throwing training, San Mao, who was sickly, accidentally dropped the Grenade and threw it into the team. Finally, he went to the front to fight. Sanmao is brave, but she also makes a lot of jokes. Somehow, he joined a death squad and even wiped out the Japanese army.

But not long after, San Mao, who was a "nanny" for the teacher, returned to the military camp because of the teacher's suicide and fought side by side with his old friends. They formed a commando team according to the orders of their superiors and then were airdropped into the jungle. But the plane never came to pick them up. Sanmao and his comrades-in-arms old ghost were almost ragged savages. Suddenly one day, a plane flew through the jungle and dropped countless leaflets. It turns out that the war is over. Sanmao became the first officer's soldier. He took off his military cap to reveal three long-lost white hairs, and he was at a loss as to where to go.
