What does thirteen o'clock mean?

13 o'clock, a Chinese vocabulary, means 13 o'clock in 24 hours, or 1 2 hours in the afternoon. As the saying goes, an idiot obviously rings the bell, and Shanghai dialect is an idiot, which comes from the Shanghai Guide, Summary of Shanghai and Soviet Dialects.

"Thirteen o'clock" originally meant "ringing the bell". In the past, the clock struck the hour.

For example, at four o'clock in the afternoon, the pendulum will strike four times, five point five times, twelve times at most, but thirteen times. Is thirteen o'clock a problem? As the saying goes, crazy! So "thirteen o'clock" is the "epilepsy" of a person's character.
