How should my mother-in-law greet her when she buys food and enters the house?

Say: mom has worked hard. Mom, come in and sit down and have a rest.

Good: Put your mother-in-law's slippers in the direction of her mother-in-law, and bring all the dishes that her mother-in-law is carrying, and classify them. If you want the kitchen, take the kitchen.

Say: (ask for instructions) What dishes shall we cook?

Ok: take out the dishes pointed by your mother-in-law and pick them up and wash them.
