What do you mean by eight characters and five elements?

The five elements of eight characters refer to gold, wood, water, fire and earth. The eight characters are calculated according to the date of birth, also called four pillars. The horoscope consists of four groups (year column, moon column, sun column and hour column). Each stem consists of heavenly stems (A, B, C, D, E, Ji, G, Xin, Man and Ghost) and earthly branches (Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai). The five elements of heavenly stems are divided into yin and yang, specifically: Jiayangmu, Yiyinmu, Bingyanghuo, Dingyinhuo, Wuyangtu, Jiyintu, Keyangjin, Xinyinjin, Renyangshui and Guiyinshui. Heaven does five elements, and the earth supports five elements. When heavenly stems and earthly branches cooperates with each other, it will become the new Five Elements, which are called "Yin Na Five Elements". Jia Zi and Yi Chou are the gold in the sea, while Bing Yin and Ding Mao are the fire in the furnace.

The four pillars, branches and five elements are: Dalinmu, Pomegranate, Sangzhemu and Daxi. The distribution details of the five elements are as follows:
