Eight doors are giants, Chai Men, hot, unpopular, back door, Longmen, knocking at the door, mountain gate. What do you mean, respectively?

Eight gates belong to each other in the five elements, with opening, breathing and life as the three auspicious gates, death, shock and injury as the three fierce gates, and Doumen and Jingmen as the general gates. Predictions are often based on their falling into the palace, that is, the birth and death of the five elements of the palace and the release of prisoners.

Giants are the homes of the rich, while Chai Men is the home of ordinary people. When something is popular, it is a hot event. When something is unpopular, it is a cold event. The back door is for yourself, leaving a way out. Longmen is the door to the success of Yuelongmen. Knocking at the door is a ritual door, a mountain door, and a door to climb high and look far.
