Literal translation is 'Big Li, Little Li, & Old Li'
Old Li, the couch potato, is the father of Little Li, and the neighbor unrelated Big Li. Old Li is also the manager of the meat processing plant where Big Li and Little Li work.
Big Li was a couch potato and whenever it was to rain, his waist hurt accordingly, hence, the nickname: weather station. Big Li would bring umbrella whenever his waist hurt, and it always worked. Other employees who worked at the same plant and lived in the same building would always observe Big Li to see if he brought umbrella or not before they went to work.
After Big Li exercised regularly, his pain went away and he became a sport enthusiast, and both he and Little Li, a strong advocate of sport and exercises, wanted to make exercises mandatory at the meat processing plant. However, they had to convince the manager, Old Li, first. A series of mishaps happened in their clumsy attempts but finally, sports and exercises were accepted and made it official.
