What if my sister-in-law doesn't like my brother and sister-in-law?

Don't think too much, people will always have ideas, but the key is to see how you look at such things. It is not your fault that you are in poor health. My mother-in-law favors my sister-in-law. At that time, because of taking care of children, there were still many feudal ideas of the elderly, and such things were not insoluble. As long as you take good care of yourself and try to have a baby on the eve of the Spring Festival, your mother-in-law won't have any problems. A good daughter-in-law is a good daughter-in-law wherever she goes, as long as she can treat me correctly, I believe you can do it! Smile at ease, hehe!
