What does it mean to be as free as the wind?

It means that a person can be as free as the wind, without any constraints, and can do whatever he wants.

Freedom like the wind means that a person can be as free as the wind, free from any constraints, and can act as he pleases. This freedom does not refer to external freedom, but to internal freedom, that is, a person's thoughts, beliefs, will and actions can be independently and freely displayed.

In ancient China, freedom also meant liberation, which meant that a person was liberated from the shackles of external forces and was able to make his own decisions. The opposite antonym is worrying, which means that a person can't do something freely and must be bound.

In a word, the wind-like freedom is an ideal state, which represents human's pursuit and yearning for freedom, autonomy and inner freedom.
