Why does my brother and sister-in-law always want to plot against my sister?

Because people's conscience is "greatly broken" haha, the reform and opening up, moral decay, only recognize money, do not recognize parents, brotherhood, has long forgotten, regard thieves as money, meticulous everywhere, regard money as their own, afraid of being exposed. Regard wealth as life, and human feelings are lost. I advise you to be patient, stay close to you less, stay at a respectful distance, as long as you have money.
