Gold shops in Hong Kong are generally priced according to the "two", which is completely different from the "two" in the Mainland.
1, the mainland's "two" is 50g, one kilogram equals twelve, and 1 kg equals 20 ounces;
2. But in Hongkong, "gold" and "beam" are traditional concepts of China. A catty is equal to 600g, and a catty is equal to 16 liang (from which half of A Jin is derived), and one or two is equal to 10 yuan.
3. Converted, one or two in Hong Kong and Macao is equal to 37.5g At present, the gold price in Hong Kong is updated daily according to the change of international gold price. Today, the price of gold jewelry in Hong Kong is 13830 Hong Kong dollars/gram, which is about 289 yuan/gram when converted into the mainland price, which is cheaper than the mainland gold price.

China appeared before the Han Dynasty, and then spread to Japan, Korean Peninsula, Vietnam and other places. The actual quality is worse from generation to generation, and it has also changed since it was spread to various places. The traditional 1 kg is equal to 16, hence the idiom "half a catty is eight liang". The 1 2 used by jewelry stores in Hong Kong and Macao is equal to 37.5g, which is different from the 1 2 currently used in China.
The ancient silver coins in China need to be appraised and weighed to determine their value. Generally, the unit of mass when weighing is "two".
