Hehe, it's very simple. Obviously, I am mainly my mother-in-law. First of all, I can be sure that my son and mother-in-law are shopping for my daughter-in-law. My son is honest and will listen to my mother in everything. Of course, after marriage, my daughter-in-law is definitely not the owner of money. My mother must have paid for it. My son can't let his mother accompany him to buy things for his wife. This rarely happens, and his son is unlikely to buy jewelry for his mother and daughter-in-law. Therefore, it is the mother-in-law who spends money and the daughter-in-law who takes things. First, determine the main goal, then how to sell things, and then maximize profits. Since things are bought for daughter-in-law, the standard of things must be whether the daughter-in-law likes it or not, and the mother-in-law helps to choose. However, you'd better ask your son to buy it for both mother-in-law and daughter-in-law. First, make things ready for the daughter-in-law, see her preferences, like the beautiful jewelry of her daughter-in-law, and then take care of her mother-in-law and control her son. A son cannot marry a daughter-in-law and forget his mother. By the way, choose one, master the temperature, see the change of mother-in-law, and recommend the right price at the right time. Hehe, let's just say that there are too many variables and many skills and methods are needed. At the beginning, you need to keep the scene happy and harmonious, which is very conducive to sales, which requires your eloquence. Clever use of relationships, I hope you can succeed, hehe.
