Development history

The concept of "midnight" came into being in the Ming Dynasty. Wang Kui's Book of Li Hai and Li Ji (see: Miscellaneous Categories in the Subdivision of Si Ku Quanshu or Introduction to the Missing Parts of Ancient and Modern Book Integration): There are different opinions about the hundred engravings, and no one can agree, and the only one is the best.

I think 60 points per hour, 6,000 points per hour and 500 points are scattered at 12, so it accounts for 8.020 points at one time. Cut eight quarters into four quarters, but divide twenty minutes into ten quarters.

Governor Zhao Yuan also said that 12 will be divided into eight quarters, 96 quarters will be counted as big quarters, but the remaining four quarters will be divided into 60 cents, four quarters will be divided into 240 cents, and each quarter will be divided into 20 cents. In this way, eight big quarters will get 20 cents, and each quarter will get 10 cents.

Everyone else gets 10 minutes at 2 noon, 9 minutes at noon and 4 minutes at midnight, all of which are wrong. However, the saying of midnight is just before midnight, so it's called midnight.
