Although people don't know much about ancient clocks in China, they know a clock 165438 built by astronomer Su Song in the 10 century. It is driven by a water wheel.
The man who changed the above situation was an outstanding astronomer in China named Yi Hang, who lived in the 8th century. Together with another China inventor, Liang Lingzan, he designed the "escapement device", that is, the cogging structure of gears in the center of all mechanical clocks.
Mechanical clocks were introduced to Europe in the Middle Ages. By the14th century, Europe had built a big and stupid mechanical clock. They are driven by a clock hammer, and the daily accuracy is within 1 hour. Such a clock is usually not credible in people's eyes. They are connected to a clock that tells the time. But since they are so inaccurate, it is impossible to display minutes and seconds in mechanical devices! /kloc-spring-driven clocks were developed in the 0/5th century, and then more accurate clocks with pendulums were manufactured in the 0/7th century. Below: A page in the old catalog shows various clocks, both spring-driven and pendulum-driven. These clocks were very popular in the19th century.
In the Middle Ages, clocks made by watchmakers could show the movement of the sun, the phases of the moon and planets and the time. The anthropomorphic organization rings the bell from time to time, and reports the time by voice and quarterly.
(2) The surname is Zhong.
The origin of the Zhong family can be directly traced back to the Song State established in the Spring and Autumn Period, and it can be counted as the descendants of Shang Tang, an ancient sage. Because their ancestors used to eat in a place called Yaozhong, their descendants took this city as their surname and began to take Yezhong as their surname. In other words, the familiar compound surname "and the single surname" Zhong "are actually the same blood family, and there is no difference between them.

Later generations or single surname Zhong, Chu has, Zhong, Zhong, and are friends with. Xiang Yu took it, named him Zhong, and began to live in Yingchuan Changshe. "
For example, in the Spring and Autumn Period, Zhong Ziqi, praised by Boya as "playing the piano and not playing drums", left many stories such as "bosom friend" and "flowing mountain" for future generations; Zhong Yi, praised as "benevolence, faithfulness, loyalty and sensitivity" by Fan Wenzi of Jin State; Even in the Warring States period, her unattractive but virtuous person was determined to "tear down Taiwan, stop women's music, retreat from flattery, keep your word, choose military forces and real treasures" because of her suggestion, and so on, the ambassador, the queen of Daan, Qi, and the "salt-free monarch" were highly respected by future generations.
Zhong You's name is even more famous, and his accomplishments in calligraphy are called "obsessed with officials and businessmen, getting eight points into the wonderful" by Zhang Huai's Broken Book. His reputation is immortal in traditional culture.
