Put out your left hand first, remember it must be your left hand.
Use the thumb of your left hand to count, and rotate clockwise in turn, starting from the root of your index finger, with the knuckles at the root of your index finger as Daan and the fingertips of your index finger as lingering, then continue to pinch the fingertips of your middle finger as Suxi, and continue to rotate clockwise, with the fingertips of your ring finger as Chikou, and then the knuckles of your ring finger as Xiaoji.
Then the last step is to return the root of the middle finger to void, and then pinch it again from Daan of the root of the index finger, that is, from the first turn of the index finger to the void of the middle finger. This order is always fixed.
The first month is Daan of the index finger root joint, and the last month is February, March of quick happiness, April of Chikou, May of Xiaoji, and June of empty death. Then it's Da 'an in July, lingering in August, and quick happiness in September ... < P > The number that circulates in this way until December is empty. For example, it's the ninth month of the lunar calendar, and counting to twenty is Chikou. Then count the hours, and the starting point of the hour is also the end of the day. Therefore, when counting the children from Chikou, the ugly time is Xiaoji, the yinshi time is Daan, and the maoshi time stays until you calculate the hours of the day.
