Ping Jin crisis! North China crisis! Chinese national crisis! Can I change seats? Why? What's the exclamation point like?

Flat metal is a part of northern China. Ping Jin is in danger, and further development will lead to the fall of North China.

North China is a part of the whole country and has also fallen. Further development will lead to the collapse of the whole country, that is, the collapse of the Chinese nation.

So this is a logical relationship.
