What do you mean by weak in eight characters?

This is a technical term, which is really difficult to explain clearly, so I can only give you a general explanation:

Physical weakness refers to the weakness of the five elements representing oneself in the eight characters. If the five elements representing you in your eight characters are wood, then weakness means that the strength of wood is weak.

Weak body and strong body (strong body) do not represent good or bad fate. Everyone is different. Some weak people have good lives, some have bad lives, and so do strong people.

The specific situation should be analyzed in combination with everyone's eight characters.

Generally speaking, many disadvantaged people have little courage, lack the right to speak, or live a passive life, and are easily influenced by the environment. But this is not universal.
