Yixing household isolation does not deliver meals.

Wrong. It is wrong for Yixing to be isolated at home and not deliver meals. If you live alone or the whole family needs to be isolated, there will be special community personnel to put food at the door, so don't worry. If a member of a family needs to be isolated, he can't eat with his family when eating. He wants to prepare bowls, chopsticks, food, wash and help himself at the door. If there are leftovers, they should be sealed and the family members should put them in the trash can. Both sides should wash their hands frequently.
