What does the central axis mean? Is the house on the central axis feng shui good?

In Zhou Li, people say: "Only Wang Jianguo can distinguish people's positions and think people are extreme", which means that the direction of the capital must be clearly distinguished. Set the correct position, that is, the central axis should be right. The so-called positive means that the central axis of the capital should be parallel to the meridian. Throughout the ages, the founding countries have carefully chosen to establish the central axis. The houses on the central axis are considered to be square, evil and auspicious. There are also different views on Zhengzhou's central axis. Some people say Zhongzhou Avenue, some people say Navigation Road, and some people say Beijing-Macao Expressway. We don't know who is telling the truth.
