The meaning of "one-two-in-one" can also be extended to the merger of two different forces or viewpoints. This merger may not be exactly the same, or even the opposite sometimes, but some people learn from each other and gradually find some similarities, thus forming a better way of thinking and action.
At the same time, the meaning of "one-two combination" can also be interpreted as the correlation of something. For example, the five elements of the human body-gold, wood, water, fire and earth-can restrict, depend on, grow and inhibit each other. This connection and balance is very important, and many fields such as ideology, culture and calligraphy art have expressed the importance of this connection force in people's lives.
