The day before yesterday, I heard a "master" say that no one can brainwash others. The so-called brainwashing is to accept new observations, ideas, or ways of thinking. So don't worry too much about your wife being brainwashed by perfect direct sales. You should communicate with your wife more and see what new observations and ideas she has accepted, and what negative effects these have brought to your's life. If not, respect her. If these have some influence on your life, then you should communicate with her on the basis of understanding. I think your wife also wants to create your business through perfect direct sales to help improve the family. This method is good and can be praised. If you don't like her doing this, you can give her some better advice.

Simply put, there are many ways to make money and improve your life. You should study more and guide her reasonably.

I wish you happiness.
