Master, help me see what the seven kills in the eight characters mean. What do you mean?

The eight characters are divided into four days (annual, monthly and daily) and four places (annual, monthly and daily).

According to the five elements and yin and yang attributes, for example, your daily dryness belongs to fire (yin) and your annual dryness belongs to water (yin). When the yin and yang properties of fire and water are the same, your dryness means that your five elements are restrained.
