Causal sentence pattern of traditional culture

I also think this is the principle of dialectics.

Causality refers to "my cause leads to your fruit", while "what is cheap is expensive, and what is expensive is cheap". There is no causal relationship between the two.

The innate dignity lies in the family, and the acquired dignity lies in oneself. Expensive and cheap are not absolute, but relative. Therefore, this should embody the principle of dialectics.
