Why doesn't the shopkeeper sleep?

Personally, before Xiao Guo came, Beckham lived alone in a room with someone to watch him, so as to cultivate his children's independence. Later, Xiao Guo came and there was no other room, so he slept together. As for the reason why the shopkeeper succeeded in reasoning every time, she read the original script. This reason was written in the script, but it was later deleted when shooting. The reason is that the shopkeeper actually knows hypnosis, but hypnosis almost killed the whole family, so she hypnotized herself and forgot martial arts. But she is very talented and can still convince others more easily than ordinary people.
