What is the harm of filling lakes and building palaces in China folk geomantic omen?

This site selection violates the basic principle of "choosing neutral palace" in China folk geomantic omen. In addition, the biggest problem in building a palace in the east of Nanjing is that there is a lake here. If you fill the lake to build a palace, it will be more time-consuming and laborious.

In addition, even if the lake is filled up, the foundation will be unstable and even sink. In this way, the palace will be high before and low after, which is a taboo in geomantic omen. This also indicates that Zhu Yuanzhang's descendants can no longer surpass him.

However, these problems were not considered by Zhu Yuanzhang at that time. By the time he woke up, the palace had been built. Zhu Yuanzhang felt very uncomfortable and always wanted to move the capital, but he never finished.

At that time, Zhu Yuanzhang had realized that the rise and fall of the dynasty had its own destiny, and he only asked God to read his sincere heart and benefit future generations.
