Feng Shui calls the rolling mountains Long Mai.
Long Mai originates from Kunlun Mountain in the northwest, and three Long Mai extend to the southeast. Bellon entered Shaanxi from Yinshan Mountain and Helan Mountain, starting from Taiyuan and ending at crossing the sea. Zhonglong entered the customs from Minshan and entered the sea from Qinshan. Nanlong entered the sea from Yunnan-Guizhou and Hunan to Fujian and Zhejiang. Every big Long Mai has dry dragons, branch dragons, real dragons, fake dragons, flying dragons, hidden dragons, flash dragons and feng shui surveys. First of all, we must find out the background and conform to the direction of Long Mai.
Since Qin Shihuang was called the "ancestor dragon" and Emperor Gaozu called himself the "dragon species", the dragon has become the symbol and object of monarchs and emperors. Thus, Long Mai has another metaphorical meaning, that is, those who used to be emperors (or maybe emperors), or who were able to bury the emperors and protect the descendants of the royal family. Therefore, the reigning emperor made great efforts to "search for dragons and explore caves" for himself, to find a "blessed land through the ages" for himself and future generations, and the so-called "burying gold and changing its name to build a temple, digging Long Mai to vent its anger" and other events.
