Can I share the first 15 days of junior high school?

There are many things that need to be avoided in China's traditional customs, such as the first day of junior high school and the fifteenth day. There are not only precautions in the custom of burning incense, but also the saying that you can't share the same room. Is superstition at work or is it really based on science? Today, Bian Xiao has compiled the agricultural calendar for you. Please see the introduction below for details.

In China's traditional concept, men and women are divided into yin and yang, men return to yang and women return to yin. Only when men and women have sexual intercourse can they reproduce. As the saying goes, "Lonely yin is not born, and lonely yang is not long." However, only sexual intercourse between men and women can achieve harmony between yin and yang. Otherwise, the disharmony between Yin and Yang will not only be detrimental to the reproduction of future generations, but also bring forth many evil consequences. Therefore, men and women should also have taboos about yin and yang when making love.
