According to the fire diagram, the query is easy to learn. Com, Tibetan trunk and earthly branch are two important numerology concepts handed down by the Chinese nation for thousands of years. Tibetan stem refers to eight heavenly stems on the four pillars of the year, month, day and hour in an eight-character character, which is called "Tibetan stem". The earthly branches refer to the twelve earthly branches, also called the Zodiac, which are rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs. As an important part of the constellation, Tibetan elephants reflect a person's fate and personality. Different Tibetan stems will have different influences on people's fate and personality, so Tibetan stems play a very important role in reading eight characters. For example, a person's eight characters have multiple hidden stems, so this person's fate is often relatively stable, and it is difficult to have big fluctuations.
