Ordinary people in Su Minfeng, cold people, hot people.

Su Minfeng's theory of "ordinary people, cold people and hot people" is based on the eight-character tone. According to this theory, people who are prepared for danger in times of peace do not avoid fire and water, those who live in cold like fire, those who live in heat like water, and those who live in gold like water. According to this theory, people's fate can be calculated by the date of birth, and people's fate is determined by the five elements, including the relationship between the generation and grams of the five elements' qi and the strength of the five elements' qi in the eight characters. Therefore, according to the eight-character calculation, we can judge a person's fate, but we can't completely decide a person's fate. People's subjective efforts and actions will also affect the development of fate.
