There is no general in Shu, and Liao Hua is the pioneer. This idiom originally revealed the historical fact of the shortage of talents in Shu and Han in the late Three Kingdoms, and later extended to mean that because there are no outstanding talents, mediocre people can be lucky enough to become famous, which is similar to the meaning of "there is no tiger in the mountains, and monkeys are called overlord".
