There is a custom in Datong that if a daughter wears a cotton-padded jacket when she goes to the wedding car, the future life will be thick, and her husband's family should symbolically put some money in her cotton-padded jacket pocket in advance to show that she will have money in the future. Many girls get married in this way, but the red cotton-padded jackets sold now are very thin, only a little silk cotton is filled symbolically, and they will be replaced immediately when they arrive at hotels or in-laws' homes. That is to say, they will only be worn like this for a while in the wedding car, which is air-conditioned and should not feel too hot. If you are holding a wedding in Datong, discuss it with your husband. If your husband's family is very particular about it, it doesn't matter if you don't pay attention to it.
