Is it true that Lao Fengxiang changed back to the original price?

This is not true. Lao Fengxiang is a well-known jewelry store. Jewelry stores of big brands don't recycle, so they need to exchange money, trade in old ones and then make up the difference. When Lao Fengxiang's diamond ring is replaced by a new one, a certain price difference will be made up according to the diamond ring price at the time of purchase (whichever is higher than the new one). The specific price depends on the new one.
