Zhanghuatai in history is also called zhanghua Palace. In fact, it is necessary and unnecessary to become a problem, just like the Lutai construction last week.

For emperors, nothing is necessary and nothing is unnecessary. They like what they are going to build. Not that every building in our country is useful, although there are many useful buildings, such as the Great Wall, which can resist the interference of Xiongnu from the outside, so we think the Great Wall is a very necessary building. But, if necessary, why build palaces and the Forbidden City?

Therefore, every building has its reasons. It has been established in history, and we can only respect it. Moreover, I think those ancient buildings, if left to us now, are also a very magnificent culture. Just like the Beijing-Hangzhou Grand Canal now, it was said that it was built by a bad king looking at flowers, but now it has provided us with a lot of help in transportation.
