What do you mean it's not sunny when it's hot?

Futian. . . . . . "crouching" means being forced to hide underground, which is the hottest time of the year. Starting from the summer, according to the arrangement of dry and branch days, the third Geng Day is the first month. The fourth Geng Day was in the middle, and the first Geng Day after beginning of autumn was the last. The word "Geng" on Geng Day is the seventh word in ten days of "A, B, C, D, E, Ji, Geng, Xin, Ren and Gui", and Geng Day is repeated every ten days. The start and end time of the dog days is different every year, roughly from mid-July to mid-August. How exactly is it worked out? China's popular "Ganzhi Diri method" records dates with 60 groups of different names, and each day with the word Gengzi is called Gengri.
