What do you mean, the lotus is standing closed and the peony is squatting open?

The phrase "the lotus closes when standing, and the peony opens when squatting" means that people will show different characteristics or performances in different environments or States.

When people stand, the petals of the lotus are closed, which can symbolize that people may keep a modest and low-key attitude and are unwilling to attract too much attention when facing ordinary daily situations or general social occasions.

When people squat down, peony flowers are in full bloom, which can symbolize that people may choose to show their talents and charm in the right time and environment.

This is a description of the complexity of human nature and a vivid description of people's different reactions in different life roles and environments.
