This lot means "知禮盡孝". It indicates that all parties involved, whether male or female, should know the rules of etiquette and practice filial piety. Confucius said, "Do not look at rudeness, do not say rudeness, do not listen to rudeness, and do not move rudely. One should be disciplined in one's actions and behavior, and not overstep the bounds of propriety in anything. Do not watch current TV programs, movies, the Internet, or books that pollute your mind and body and give rise to delusions and evil thoughts. Do not talk about the shortcomings of others, do not boast about your own strengths, and do not pry into the secrets of others. When others gossip or speak of private matters, if it does not concern you, avoid them at a distance and do not listen to them. Do not do anything against morality and conscience. To be sincere, respectful, and considerate of others in all things is to know how to be courteous. To be filial is the foundation of a person's character, and one must never forget the debt of gratitude one owes to one's parents for their support. Do not worry about your parents in any way, and always be concerned, inquire, and pay attention to them. It is not limited to monetary offerings. To be courteous and filial is the foundation of morality, and it will not change even if the times change.
