Why should rice vats and granaries be placed in the northeast and southwest?

The Chinese food structure is basically based on carbohydrates and chlorophyll. That is to say, the main intake is whole grains, vegetables, and fruits, and the intake of meat and eggs is relatively small. Therefore, the body shape and quality of Easterners are different from Westerners. Even Chinese people are divided into northerners and southerners. Northerners like to eat pasta, while southerners like to eat rice, so every household has rice vats and noodle cabinets (cylinders) to store food. In addition, the Chinese have the habit of "accumulating grain", so they attach great importance to the storage location of rice vats and noodle cabinets. The traditional theory of Kanyu believes: "The rice warehouse (rice vat) is the place where grain is stored, and the five elements belong to earth. Therefore, no matter where you sit, building a (house) on earth is a great benefit. And it cannot be placed on the wooden side of the house..." According to " The principle of the Bagua in the Book of Changes is that the north is Kan Gua, the five elements belong to water; the east is Zhen Gua, and the five elements belong to wood; the west is Dui Gua, and the five elements belong to gold; the south is Li Gua, and the five elements belong to fire; the northwest is Qian Gua, and the five elements belong to fire. It belongs to gold; the southeast is Xun Gua, and the five elements belong to wood; the northeast is Gen Gua, and the five elements belong to earth; the southwest is Kun Gua, and the five elements also belong to earth. Therefore, the ancients used to place rice and noodles storage utensils in the northeast and southwest of the house. It is taboo to place it in the east and southeast. Philippine Feng Shui master Xu Shaofeng believes that the northeast and southwest directions of the house have less sunshine and little temperature change, so they are very suitable for placing rice jars and noodle cabinets to store grain. Especially the northeast direction is more suitable. The east and southeast directions have more sunshine, relatively high temperatures, and large temperature differences, so these two directions are not suitable for storing grain.
