Ancient books describe military capabilities.

Before the Tang Dynasty, there was no word "tea". At that time, tea was called tea, which was the top name of tea. However, if "in full swing" and "as hot as tea" mean the same thing, it is all wet. "Tea" is not only the meaning of tea, but also the word "tea" in In Full swing does not refer to tea. The original meaning of "in full swing" is red as fire and white as tea (a kind of thatched white flowers), which is a metaphor for military capabilities. now
