You shouldn't ask the child whether it is yin or yang, but whether the child belongs to yin or yang. Neutrons in the twelve branches belong to water and belong to the north. In divinatory symbols, every direction has two attributes: yin and yang. The north sea is overcast water, and the son is sunny water. Hai is the gathering of all things and yin; The son is the beginning of all things, and the yang is also.
