What do you mean by not going out on the seventh day and not coming back on the eighth day?

As the old saying goes, "Don't go out for seven days" doesn't mean that you don't go out on the seventh, seventeenth and twenty-seventh day of July, but that you don't go out until you do 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.

Eight don't go home means "eight" means "filial piety, faith, courtesy, honesty and shame", and "eight don't go home" means these eight basic principles of being a man. As long as one of them doesn't do well in the exam, he will be ashamed to go home to meet his parents.

With the change of society, especially the richness of material, people will not be affected by the "seven prohibitions" when they go out. But "eight don't go home" can still be advocated, because these are good guidelines. If these eight aspects can be done well, they can be called "moral models".
