Is an hour four or eight hours?

In China, whether ancient or modern, one hour is two hours 120 minutes. In ancient times, an hour was divided into eight major moments and two minor moments. The major moment was 60 minutes, and the minor moment was 10 minute, so a day was 6000 minutes (modern people were 1440 minutes), that is, 10 minute. First time 10 minute, first time 60 minutes, second time 60 minutes, third time 60 minutes, fourth time 60 minutes, first time 10 minute, second time 60 minutes, third time 60 minutes, fourth time 60 minutes, big time10 minute. The Qing Dynasty didn't change it into an internationally unified time-keeping method, that is, 24 hours a day, 1 hour, 4 minutes, 1 minute, and 1 hour in China is exactly two hours, so one hour and eight minutes are called a quarter of an hour, two minutes, three minutes, … eight minutes respectively, regardless of the exact time. This is. Three minutes at noon is 1 1: 45, and 12: 45 is seven minutes at noon. This is a modern saying after the late Qing Dynasty. It is said that three minutes at noon in ancient times was a lie, which was invented by the screenwriter and director.
