What is a birthday? What are the five elements? When was it all?

Hello, landlord, birthday, this is another way of saying "four pillars" in Zhouyi. Four pillars refer to the time when a person was born, that is, year, month, day and hour. When people use "heavenly stem" and "earthly branch" to represent year, month, day and hour respectively, such as Jiazi Year, Shen Bingyue, Guichou Day and Renyin Time, it contains the basic state of celestial movement when a person is born. Two words in each column and eight words in four columns are called eight characters.

The five elements refer to five basic substances, namely wood, fire, earth, gold and water, and their movements and changes. The five elements are gold, wood, water, fire and earth, and they are related: gold produces water, because the most primitive water on the earth is transformed from the inside of the earth; 00 aquatic wood, because water irrigates trees, trees can flourish; 00 wood is used to make a fire, because the fire is fueled by wood. When the wood is burned out, the fire will automatically go out. 00 fire produces soil, because after the fire burns the object, the object becomes ashes, and the ashes are soil; 00 natural gold, because both soil and stone contain gold, and metal is extracted after smelting;
