What meteorological measuring instruments were there in ancient China?

China was the first country to invent anemometer and rain gauge. Zhang Heng of the Eastern Han Dynasty invented the waiting seismograph in 132. It stands a 5-foot (about 16.7 meters) high pole with a rotatable copper bird on it. According to the direction in which the bronze bird rotates with the wind, we can see what the wind direction is. This is similar to the waiting for chickens recorded in foreign books in 12 century, and it is later than the bronze bird 1000 year.

There was also a wind flag in ancient China, which was tied with a Jason Chung and hung on a high pole. You can tell what wind is blowing by looking at the direction in which the flag is blowing. This is similar to the modern wind pocket.

China first used the rain gauge. There is a passage in Shu Shu Jiu Zhang that describes the situation from 65438 to 0247 AD in the Song Dynasty. The rain gauge is uniform in size, with a cylinder diameter of 14 cm and a copper rain gauge.
