This is because in the traditional culture of China, the southwest is considered as an auspicious direction, which accords with people's yearning for a better life.
In addition, walking along the forest in the southwest direction is also in line with the traditional geographical feng shui theory and is conducive to the harmony and stability of the living environment.
In a word, future generations should respect and follow the traditional behavior of their ancestors, so as to inherit and carry forward the excellent Chinese culture.
