In superstitious customs, besides the saying "Chong Xi", there is a similar saying called "Xi Chong Xi", but the result is the opposite. It is said that "happiness rushes to happiness", that is, two happy things happen at the same time, which will produce "violation" and bring misfortune. In order to avoid "happiness rushing to happiness", people think it is not appropriate for a family to hold two weddings a year; Newcomers should not attend other people's wedding banquets within one month before and after the wedding, so as not to offend; In addition, the wedding cake sent by the man should not be eaten by the bride-to-be and the groom, so as not to bring bad luck; In addition, it is best for pregnant women to avoid attending weddings or wedding banquets, because the "bride god" is bigger than the "fetal god" and the happy result is not good for pregnant women; At the same time, pregnant women should not enter the bride's room less than 4 months after marriage, and newly married or prospective brides should not enter the woman's room less than 4 months after giving birth, so as to avoid adverse consequences for both parties. If the sedan chair (limousine) meets the sedan chair (limousine) on the way to the wedding, it will be considered as "beaming" and will lead to bad luck. At this time, as long as the matchmakers of both sides exchange flowers prepared in advance, it is said that bad luck can be resolved. This doesn't seem to be a big problem.
