On bikes, colour matching with their helmets and t-shirts, Hoda, Jinbao und Panxing ride to the river in their holidays. They go swimming and fool around with Jinbaos swimshorts. Finally Jinbao has to catch his shorts from them, bare-assed. An elderly angler is affected by them very coarsely and finally the four of them bump their heads into each others' accidentally, so that the old man falls unconscious and the three boys take flight with horror!
Conscious-stricken they "submerse" at an aunt's house, but that doesn't really work. While one plays with ducklings at his grandmother's house, the other two feel responsible for the moneyless and now lonesome granddaughter of the old man and also for him, who suffers from amnesia since the accident.
They help in taking care for the old man and find jobs, so Youyou can go on with her pipa-lessons. (The pipa is a traditional chinese string-instrument).
Finally the three boys want to make good for everything and start playing the scene to the grandfather, which has caused the crash: finally successfully. The old man recovers from his amnesia!
The 42-year-old director has made her third film for young people, after a well known chinese book for young people. She chose the young actors from the face, in schools in her county. All of them stood in front of the camera for the first time. The movie is made in only 25 days. With very simple subjects she shows, how the boys overcome their fears and finally succeed in facing liability and the possible consequences of their mishap.
Additional information I gathered from the audience talk: The brown eggs have been drained in tea or soy sauce and then have been boiled, ten Yen approximate one Euro and in Chinese cities, there are little parts of traditional Chinese Opere are being shown on public places during the day.
