The horoscope master Guishui was born in the Chou month. The water is cold and the earth is frozen. He urgently needs fire to adjust the weather. Unfortunately, there is no spark at all in the horoscope, so he can only use wood to make fire. The problem of internal heat may be mainly caused by the kidneys. You can go and have a look. It's cold.
You can read the wood chapter and fire chapter of the Five Elements Transformation Method in my space, which may be helpful.
