What is "He Shi" in Feng Shui?

The so-called "Heshi" means that the sum of two numbers is ten, which means Heshi. In the Houtian Eight Trigrams, the hexagrams represented by the Heshi number are opposed to each other, such as Yikan and Jiuli, Erkun and Bagen, and Sanzhen and Qi. In contrast, Si Xun and Liu Gan are in opposition. Xuankong Fengshui believes that the union is a sign of auspiciousness. In the natal chart, the union of Xiangxing and Yunxing, or the combination of Shanxing and Yunxing, or the combination of Shanxing, Xiangxing and Yunxing are all signs of good luck. However, if you encounter a pattern where the double stars will sit up and down, and there is no water behind, although the plate is full, it is not lucky.
