Finding Masao's behavior weird, Shin chan and his friends decide to follow. Masao goes through a street, which leads to a China-town. In that town, they found Masao practicing by balancing a water bowl on his head. When Shin chan shouted, he told them that he was learning the Chinese Martial arts named Kung Fu. Then they met the master and Ran chan (who was masters first student). They found that Shin chan was very soft to learn Kung Fu and wanted him to learn it to.
