"Swollen in head, weak in legs, sharp in tongue but empty in belly"

This quote from Mao Tse-Tung describes individuals or groups with inflated egos (inflamed in head) and a desire for power and influence, however who do not have the capability to back it up (weak in legs). These people or groups may fast to slam or attack others verbally (sharp in tongue) however are lacking in compound or accomplishment (empty in stomach). Overall, the quote recommends that a focus on empty rhetoric and ego is eventually worthless without any compound behind it.
