There are three kinds of unfilial, which means:

1. The first unfilial means: knowing that your parents have done something wrong, you still obey and cater to them, and as a result, you are caught in injustice, which is a manifestation of unfilial. During the Warring States Period, there was a famous soldier named Kuang Zhang in the State of Qi. His parents fell out, and his father killed his mother and buried him under the stable.

If you don't stop the parents from falling out, and the mother is killed by her father, then it's unreasonable to let her be buried under the stable after her father's death. It is unfilial to indulge one's father in evil and give him an unjust reputation.

2. The second unfilial is that a person was born in a poor family, but still attached to the warmth of his family and refused to go to the society to struggle. According to the ancients, it is called "not seeking an official position", which is very unfilial. This one is easier to understand, because if a woman wants to show filial piety, she should give her parents a better life. "Caring for the old" and loving home can be understood as staying at home and "gnawing at the old".

3. The third unfilial is what people think is the most serious one-no empress. No queen means no son. China people pay the most attention to the inheritance of patriarchal clan system. On holidays, weddings, funerals and sacrifices to ancestors must be presided over by men in the family. If you don't have a son, you will "break the incense." It's like being childless.

Extended information:

The original meaning of "there are three kinds of unfilial, and there are many kinds of unfilial, and there are more serious ones." It is not that there are only "three kinds" of unfilial situations, among which the most unfilial is no empress.

Since Zhao Qi annotated Mencius in the Eastern Han Dynasty, the correct understanding of "there are three kinds of unfilial" has become: knowing that parents have done incorrect things and not stopping them; Knowing that the family is poor, they still don't want to make progress and refuse to work hard to improve their living environment; Not getting married and having children leads to no one presiding over the sacrifice at home. There is no successor in the family.
