The eight characters refer to: Xin, Mao, Ding, You, Geng, Wu, C and Zi respectively.
These eight characters respectively represent the year, month and date, such as Xin Mao for the year, Ding You for the month, Geng Wu for the day, and Bing Zi for the time. The image of eight characters is different from the image of Zhouyi in terms of composition. The Book of Changes uses yin and yang and the hexagrams composed of these two hexagrams as images, and the eight characters are composed of Chinese characters as symbols. From this point, the eight-character image is more similar to the image of traditional Chinese medicine.
Although it is composed of Chinese characters, this Chinese character is actually a symbol here, not a common language or a sentence. It's just an elephant. The eight characters are essentially the same as the hexagrams in Zhouyi, except that it uses Chinese characters instead of the symbols of yin and yang to form the hexagrams.
birthdates's role
1. Name by eight characters
Through birthdates, you can understand the characteristics of Yin and Yang and the five elements, so that when you name, you will have a certain basis. For example, if you know your own five elements, if you have your own LMNT, you can add the word gold to your name. Help yourself to get a balance of the five elements. When the yin and yang elements are balanced, the positive energy of the individual will begin to enter a good state, so in the future life, you will have a good development fortune.
2. Confirm the marriage of husband and wife
Marrying through birthdates is something that many couples are willing to do, because we can know whether the five elements of two people are in conflict or not, and whether the eight characters of two people match or not. If the birthdates of two people can be well integrated and complement each other, there will be no conflict and collision between the five elements of Yin and Yang. Generally speaking, it means that two people have a very good marriage life, and their future personal development fortune is also very strong, and both of them can promote each other.
