How much was 22 taels in ancient times?

During the Zhenguan period of the Tang Dynasty, one or two pieces of silver could buy 200 dou meters, and ten dou meters were a stone, which was equivalent to 59 kilograms now. You can buy 1 180 Jin of rice by counting one or two pieces of silver. Now rice is calculated according to two yuan a catty, so one or two pieces of silver in the early years of the Tang Dynasty are equivalent to more than four thousand dollars now, and two pieces of silver are more than eight thousand dollars.

According to "History of Song Dynasty", the price of rice in Song Dynasty is about a bucket of rice in 600 yuan, and one or two pieces of silver can buy 4 to 8 stone meters. A stone of rice in the Song Dynasty weighed about 66 Jin, and the current price of one or two pieces of silver was about 924 to 1848 yuan. Two ounces of silver are between 1848-3696 yuan.

In the Qing Dynasty, due to a large amount of overseas funds flowing into China, the value of silver fell again, and the purchasing power of silver was only one third of that of the Ming Dynasty, so it can be inferred that the value of silver in the late Qing Dynasty was only equivalent to more than 400 yuan now.
