"The collection of the seventy-two seasons of the lunar calendar": "in the middle of April, when things are small and full, things are small and full."
　　At this time, the grains of summer crops such as wheat in northern China have begun to be full, but they have not yet matured. They are about the later stage of milk ripening, so they are called Xiaoman.
　　The Southern Agricultural proverb gives Xiaoman a new meaning: "Xiaoman is dissatisfied and breaks the ridge of the field"; "If Xiaoman is dissatisfied, grain in ear doesn't care". "Man" is used to describe the surplus and shortage of rain. It is pointed out that if the field is not full of water when it is small, it may cause the ridge to dry and crack, and even rice can not be planted when it is in ear.
