May offend: mocks disability
Meaning
Describes someone whose skill looks modest when they start a task. The joke is that short Wu Dalang can't raise his hands high; "high" also means skilled.
Wordplay
高 (gāo) means both physically high and skilled or superior, so "his hand isn't high" also means "his skill is low."
