What is the history of clocks and watches in China? What are the evolutionary history of clocks and watches?

The main evolutionary history of our clocks and watches in China began with the sundial, because the sundial can be regarded as the beginning of our clocks and watches, because people in China used to count time by the poles of the sun.

Then the machine clock, then the wall clock, and then our electronic clock. Now everyone's clock is a mobile phone.

The development of clocks and watches can also show the progress of our science and technology. In fact, this is not only the evolution and change of clocks, but also the change of our human lifestyle. With the progress of our science and technology, the living environment is getting better and better, and more high-tech products are gradually derived.

I don't think there will be any new clocks in the future. The changes of clocks are constantly developing and changing.
