Describe yourself as skilled but laugh at others' unskilled words.

Only a few people are less skilled than others.

Ability is not blowing, trains are not pushing, Mount Tai is not piling, and gourds are not rolling.

Heaven does not speak from a height, man does not speak from a height, water does not speak from a height, and bricks are thick and thin. Arrogance stinks.

Refuse to accept the guilt of the superior.
