How to deal with calculating parents-in-law

There are many differences between your parents-in-law and your personality habits, which is quite contradictory to you. You can remind them of some practices, but they are your elders and have been used to it for many years, and may not change much. They are still strong people, and if they are given too much pressure, the contradictions will increase a lot, which is even worse. Anyway, they only come to your house occasionally, so you can bear it and remind them at the same time. More tolerance will lead to fewer contradictions. Everyone has troubles in his life, and he should eat whatever he should. It doesn't matter if you don't suffer.
