My wife has become a low-headed family. How can I bring her back?

I have a better idea: you should show your head lower than her in front of her.

It doesn't matter at ordinary times, but as long as she is by your side, you must let her see that you have been watching your mobile phone, playing games and sending messages all the time.

Only by making her realize how bad it is to do so and seizing the opportunity to educate her, she will naturally get better, otherwise the other way is just to treat the symptoms rather than the root cause.
