50 grams. It varies from place to place. In Taiwan Province Province, Sima said that one or two ounces of gold is equal to 31.25g, and in Hongkong, one or two ounces of gold is equal to 37.5g.. Shops like Chow Tai Fook are all based in Hong Kong. That's 37.5 grams. One or two ounces of gold is one or two ounces of gold in Chinese mainland, so one or two ounces of gold equals 50 grams. But in neighboring countries and regions, the concept of gold is different in different places. So, how many grams of gold do they have? "Gold" transaction in Hong Kong market: one sixteenth of Sima Jin, about 37.8 grams. In precious metal trading, the use of "Terroy" is 37.429 grams.

_ Rudder, three persimmons

1. There were many monetary units in ancient China, which were different in each dynasty, especially before Qin and Han Dynasties. Only three basic units are discussed here: a piece of paper for making money (that is, a standard square hole copper coin), a silver and a gold. Although the units in the past dynasties are different, at least there is little difference after the Tang and Song Dynasties, so relatively stable and reliable data can be obtained. The exchange ratio between copper coins, silver and gold, just like the current foreign exchange price, is constantly changing, unlike 1 yuan is equal to 100. Because money made of gold, silver and copper is valuable in itself, theoretically the value of money should be equal to the price of metal. In ancient times, although the weight units of "two" were different, they were all about 40 grams, while "Jin" was about 700 grams. Many historical monographs directly measure monetary relations through food prices. Although considering food prices alone is not accurate and objective, it should be an extremely important reference.
