— The corresponding relationship between the twelve hours and the five elements
The hours of the Metal element: You hour, Shen hour.
The hours of the Wood element: Mao hour, Yin hour.
The hours of the Water element: Zi hour, Hai hour.
The hours of the Fire element: Wu hour, Si hour.
The hours of the Earth element: Chou hour, Chen hour, Wei hour, Xu hour.
— The relationship of mutual generation and overcoming among the five elements
Mutual generation of the five elements: Metal generates Water, Water generates Wood, Wood generates Fire, Fire generates Earth, Earth generates Metal.
Mutual overcoming of the five elements: Metal overcomes Wood, Wood overcomes Earth, Earth overcomes Water, Water overcomes Fire, Fire overcomes Metal.
Therefore, people born in the "Chou" hour belong to Earth, and people born in the "Wu" hour belong to Fire. According to the relationship of the five elements, Fire generates Earth, so it is appropriate for a woman born in the "Chou" hour to be with a man born in the "Wu" hour. However, judging whether two people are compatible solely based on their five elements is very one-sided and cannot play a decisive role. Therefore, whether a woman born in the "Chou" hour and a man born in the "Wu" hour are compatible still needs to be determined based on their specific birth charts.

A man born in the "Wu" hour, as he belongs to the Fire element, will have an attractive appearance, but when interacting with others, he often lacks the ability to express his emotions. Therefore, people born in this hour tend to prefer finding a quiet and elegant place to express their feelings towards their partner.
A woman born in the "Wu" hour usually has a fresh and beautiful appearance and a wise mind, so she can attract the affection of the opposite sex in life. However, due to her inability to express her emotions well, she expects her partner to open up first.
