Checking the five elements according to the date of birth can be achieved through the corresponding relationship between the heavenly stems and earthly branches. The following is the method of checking the five elements according to the heavenly stems and earthly branches: 1. First, determine the heavenly stems and earthly branches of the year of birth. The Heavenly Stems include A, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui; the Earthly Branches include Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai. You can find the corresponding heavenly stems and earthly branches according to the lunar year. 2. Then, determine the five-element attributes of the year of birth based on the five-element attributes of the heavenly stems and the five-element attributes of the earthly branches. The attributes of the five elements of the heavenly stems are: A, Bing, Wu, Geng, and Ren belong to Yang wood; B, Ding, Ji, Xin, and Gui belong to Yin wood; Bing, Wu, Geng, Ren, and A belong to Yang fire; Ding, Ji, Xin, and Gui belong to Yang fire. Gui and B belong to Yin Fire; Wu, Geng, Ren, Jia and C belong to Yang Earth; Ji, Xin, Gui, Yi and D belong to Yin Earth; Geng, Ren, A, C and Wu belong to Yang Metal; Xin, Gui, Yi, Ding, and Ji belong to the yin metal; Ren, A, Bing, Wu, and Geng belong to the yang water; Gui, Yi, Ding, Ji, and Xin belong to the yin water. The attributes of the five elements of the earthly branch are Zi, Wu, Mao, You, Chen and Xu, which belong to Yang wood; Chou, Wei, Si and Shen belong to Yin wood; Mao, You, Chen and Xu belong to Yang fire; Chou, Wei, Si and Shen belong to Yang fire. Yin Fire; Chen, Xu, You and Mao belong to Yang Earth; Chou, Wei, Si and Shen belong to Yin Earth; Xu, You, Mao and Chen belong to Yang Metal; Chou, Wei, Si and Shen belong to Yin Metal; You and Mao , Chen, and Xu belong to Yang water; Chou, Wei, Si, and Shen belong to Yin water. 3. Finally, find the corresponding five elements according to the attributes of the five elements of the heavenly stems and earthly branches. According to the mutual restraint relationship of the five elements, the five element attributes of the birth date can be judged. It should be noted that the above method is only suitable for checking the Five Elements attributes based on the year of birth. If you want to check the Five Elements attributes based on the month, day or hour of birth, you need to perform corresponding calculations.
