What is the design purpose of the sundial?

1 A sundial instrument, also called a sundial, is an instrument for observing the time of the sun's shadow, which mainly specifies the time or minutes at that time according to the position of the sun's shadow. It is a widely used timing instrument in ancient China. In principle, it can be timed according to the length or direction of the shadow, but it is more convenient to time according to the direction of the shadow. Therefore, the timing is usually based on the position of the shadow. Because the sundial must rely on sunlight, it can't be used on cloudy days and nights. Therefore, it is not enough to use the sundial to time, and other kinds of timers, such as water clocks, are needed to cooperate.

There is also an exquisite electronic system installed in it. Whenever the hour comes, it will broadcast the time to passers-by with sound. The surrounding lighting system will make the sundial have different views during the day and at night. The surface of the coffin is engraved with 24 solar terms and heavenly stems and earthly branches. The exquisite pictures and characters carved around the sculpture vividly show the historical changes of human timing methods from ancient times to the present.
