Difference of water control from Yilong to Shierlong in 2025-2030

From 2025 to 2030, the difference between Yilong and Twelve Dragons lies in the number of hoses. It depends on how many dragons control the water, which is determined according to the first day of the first month of each year (that is, the Dragon Day of the China Zodiac). It is decided that 2022 is the year of Renyin, and the first day is the eighth day of the first month, so it controls water for the Eight Dragons. It is said that the more dragons there are, the less rainfall there will be. The fewer dragons there are, the more rainfall there will be.
