I'm engaged, not married. What does it mean that my mother-in-law will always send articles and videos of her son and daughter-in-law filial piety to her mother-in-law in the circle of friends?

Actually, it has a lot of meaning. What the onlookers say is not necessarily the real reason. Although you are engaged, your running-in with your future mother-in-law has just begun. I think it's necessary to know your mother-in-law's personality from your boyfriend, or through other appropriate channels, from acquaintances in your mother-in-law's previous unit. Know your mother-in-law's character. Because if this pimple is not solved, it will become a shadow that has been hanging over you. Know the real situation and then prescribe the right medicine. As long as you and your boyfriend really love each other. These problems can be overcome.
