Unfilial: you can't be close to your parents (honor your adoptive parents and love your family).

Second, unfilial: you can't serve the monarch (keep your duty and act loyally).

Three unfilial: you can't stand on the street and be a virtuous gentleman.

"There are three unfilial" comes from Mencius, which is what Mencius said when evaluating Shun's marriage.

Extended data:

"There are three kinds of unfilial, and it is great if there is no heir", a famous saying that people often hang on their lips comes from Mencius and Li Lou, who commented on Shun's marriage. The complete sentence is like this: "There are three kinds of unfilial, the greatest is no heir, and you don't sue if you marry. For no heir, a gentleman thinks that you still sue." This sentence is usually interpreted as: there are three kinds of unfilial, among which childlessness is the most important.

If you want to marry, you should tell your parents first. Shun married Yao's second daughter and didn't tell her parents, just because she was worried about her offspring, so in the eyes of a reasonable gentleman, although she didn't tell her parents, it was the same as telling her parents. Later generations have different interpretations of the original intention of Mencius dialect, and the disputes mainly focus on "three" and "no queen". In fact, Meng only said "nothing serious", but did not directly point out two of the "three unfilial". Until the Eastern Han Dynasty, a Confucian scholar named Zhao Qi made a supplement for him.

Zhao Qi said in the annotation of Mencius: "There are three kinds of unfilial: A Yi is obedient, trapped in injustice and unfilial; Poor old people, not an official, unfilial; If you don't marry and have no children, you will never be worshipped by your ancestors, and you will be unfilial. " Its meaning is: blindly obeying, seeing that parents are at fault and not persuading them, making them fall into injustice, which is the first kind of unfilial; Poor family and elderly parents, but not to be an official to support their parents, this is the second kind of unfilial; It is the third kind of unfilial to not marry and have children and cut off offspring.

Later, Zhu's Mencius Justice in the Song Dynasty put forward two other unfilial things: one was "being poor and not being an official", the family was poor and did not go out to be an official and get rich to adopt parents, and the other was "trapping parents in injustice". In addition, Mencius said that "there is no queen", which constitutes three things of "unfilial". "However, it is basically based on Zhao Wei's three filial piety." Professor Xie also pointed out that some people interpret the meaning of "three" in Mencius' mouth as "many" instead of the specific number "three"
