The clock face is inlaid with Arabic numerals, and Ju Ming is using the clock to promote this thing.

There are also notices posted below the bell tower to teach people how to tell the time.

I just heard a scholar read: "This big clock divides morning and evening, and the hand moves one o'clock to make one hour. The vertical one is one, and the earlier one is 'Zi Chu'. The one that looks like a duck is two, and the two o'clock early is 'Zi Zheng'...

…”

In the Song Dynasty, the twelve hours were refined into twenty-four hours.

For example, the hour of Zishi is divided into two hours: Zichu and Zizheng.

In order to adapt to people's habits, Ju Ming moved the modern hour as a whole by one hour.

In Ju Ming's version of the clock, "1 o'clock" is directly above "12 o'clock", but it represents "11 o'clock" in modern time.

It seems complicated to modern people, but it was very intuitive to ancient people.

When the hour hand moves to a point directly above, the beginning of the sub-hour (or the beginning of the noon hour) begins. When the hour hand moves to the two o'clock position, the time of the sub-hour (or the beginning of the noon hour) begins.

The beheading will be carried out at three quarters in the afternoon, and preparations can be made when the bell rings.

On the first day when the four-sided clock started telling time, groups of people came to watch the excitement.

There were also people who stayed there specially, looking up from time to time to observe, and found that the hour hand was indeed moving slowly.
