The first way is to get a commission per gram. For example, every gram of gold is sold at a commission of 3 to 5 yuan. This kind of jewelry, such as necklaces and bracelets, needs tens of grams. That is to say, a business like this, if it is concluded, can withdraw about 100 to 150 yuan. There is another way to get a commission, that is, according to the thousandth system, such as 100 yuan. Some gold shops have their own rules, but there is little difference.
