According to the records in Feng Shui of Gas Field and Feng Shui of Shigong, the river map that we have spread to the world at present is the one written by Zhu in the original meaning of Zhouyi in the Southern Song Dynasty, which belongs to the misunderstood river map. The real river map is recorded in Feng Shui of Gas Field and Feng Shui of Shigong.

The versions of Hutuluo circulated in today's society are all written by Zhu, a great scholar in the Southern Song Dynasty, and his disciple Cai.

After the Tang Dynasty, Zhu in the Southern Song Dynasty and Cai in the Northern Song Dynasty explained the principle of Heluo, from Yongle Dadian in the Ming Dynasty to Sikuquanshu in the Qing Dynasty. For thousands of years, although people have been exploring and studying Hutuluo, so far no one knows what the essence of Hutuluo is. However, there is no reasonable explanation in Feng Shui books of past dynasties. How big is the practical application of Hutuluo in Feng Shui? Today, with the development of science and technology, no one in various schools of Feng Shui books can give a correct explanation and specific application to the application of Hetuluo calligraphy in Feng Shui, because the principle of Hetuluo calligraphy used by various schools of Feng Shui is a continuation of the past erroneous cognition, and the real river map has never been exposed in society for more than 1000 years since the end of the Tang Dynasty.

In A.D. 1 193, Cai, a disciple of Zhu Ming, entered Shu from the Three Gorges of the Yangtze River, looking for two wordless gobbledygook books, River Map and Luoshu. (But on the way, he got a Hetuluo script from a minority (probably Miao or Yi). When he met Zhu, he only gave the book of Hutuluo found in Shu. After Zhu got the book of Hutuluo, he studied these two pictures for a long time, but he couldn't solve the real mystery of Hutuluo. Finally, he died with regret, resulting in Zhu, who was called "Ya Sheng" at that time, leaving a gobbledygook with no words and chaotic numbers for future generations. In fact, many great scholars in the Southern Song Dynasty disputed Zhu's version of Hutuluo, but it was eventually recorded in history by Zhu's version and spread to this day.

Although the descendants have been making unremitting efforts to study Hutuluo for hundreds of years from the Southern Song Dynasty to the present, there has never been a new breakthrough because of Zhu's misleading.
