Why can't I go to someone's house for dinner on the seventh day?

There is no such custom.

There is a saying that "seven don't go out, eight don't go home", but "seven don't go out" doesn't mean don't go out on the seventh, seventeenth and twenty-seventh day of July, but don't go out until you have done seven things well.

Seven things are what we usually say: "seven things to open the door" and "rice, oil, salt, sauce, vinegar and tea", because most of the people who went out in ancient times were men, and men were the pillars of the family. Prepare these daily necessities for your wife and children before you can go out with peace of mind.

China's 5,000-year-old civilization is extensive and profound, and every old saying handed down has its profound meaning. You must never be labeled as a feudal superstition and killed with a stick. We should not underestimate ourselves and forget the lessons of our ancestors.

Don't misunderstand the true meaning of "seven don't go out, eight don't go home". Going home is the best gift! This ancestral motto should also be kept in mind at all times, inspiring us to face life more actively and hard!
