《韩非子·扬权》
君主经常劈削树木，不要使臣下枝粗干细；臣下枝粗干细，将会经不住春风；经不住春风，树枝将会损害树心。
数披其木，毋使枝大本小；枝大本小，将不胜春风；不胜春风，枝将害心。
The monarch should always trim the branches, do not let their subjects have thick branches and slender trunks; if the subjects have thick branches and slender trunks, they will not be able to stand the spring wind; if they cannot stand the spring wind, the branches will harm the core of the tree.
