How should I deal with superstitious mother-in-law?

As the saying goes, "a leopard cannot change his spots." Your mother-in-law is in a superstitious environment, and superstitious thoughts are deeply rooted, so it is difficult to change her. In fact, my mother-in-law burned incense to worship Buddha and asked "Xian" on her own initiative for the good of her grandchildren, but this method has not been recognized and accepted by you who are not superstitious. Since it is difficult to change the mother-in-law, it is better to turn a blind eye, the mother-in-law worships Buddha, and you take your son to see a doctor; When the son is healthy, the relationship between mother-in-law and daughter-in-law will not be contradictory. As the saying goes, "When in Rome, do as the Romans do", even if you are not superstitious, don't blame or dislike your mother-in-law's superstition. Family harmony is most important.
