How to explain the communication between the East and the West in the sunny year and the communication between the North and the South in the cloudy year?

Specifically, the positive year refers to the year of "methyl propargyl alcohol" and the negative year refers to the year of "methyl propargyl alcohol". In the year of the sun, the direction of taking the three evils and going to the three evils is east-west, so people think that the year of the sun is suitable for east-west activities, such as burial and marriage. Similarly, the direction of sitting in the three evil spirits and going to the three evil spirits in a cloudy year is north-south direction, so people think that the cloudy year is suitable for activities in the north-south direction.

Generally speaking, "sunny days are beneficial to the east and west, and cloudy days connect the north and the south" is a folk saying based on China Feng Shui, which reflects people's concept of the relationship between time and space and fortune. However, it should be noted that this is only a traditional concept and has no scientific basis.
