Interpretation: According to the horse in China's chess game, for example, the bridge returns to the bridge, and the road returns to the road, each going its own way and having nothing to do with each other.

This word is a chess rule, and the word "horse walking on the sun" is like walking on the Tian Zi, which is also an idiom.

Similar chess formulas are:

Horses are cavalry, so they are straightforward and oblique, so they go to the sun.

As a strategist, he guarded the camp, so he went to other places.

The car is a chariot, and it is on the rampage, so go straight.

A cannon is a cannon, and it is called a mountain, because it is fought far from a distance.

Scholar is a bodyguard, so he is on the edge of the general.

Of course, a piece like Jing Ke is gone forever.
