I read "Zengzi Killed Pigs to Build Faith" and learned that Zengzi was an honest and trustworthy person. Zengzi set an example of trustworthiness for his children from an early age. We should keep it in mind and never forget it forever. Moreover, Zengzi used his own actual actions to prove Confucius’ famous saying: words must be deeded, and deeds must be resolute. The meaning of this sentence is that integrity is the basic principle of life and an important criterion for interpersonal communication. I also learned that Zengzi’s wife was a person who knew her mistakes and could change them. Although Zengzi’s wife deceived her children at the beginning, she finally changed her mind after listening to Zengzi’s words. This kind of spirit is admirable. It really looks like Lian Po, the great general of Zhao State during the Warring States Period! If you know you are wrong, correct it. If you know your mistakes and can correct them, there is no greater good. Zengzi and his wife also told the villagers to teach their children to lead by example, so that their fellow villagers would also become honest and trustworthy people. Zengzi's practices have been passed down to this day, and his character has always been respected and loved by future generations. This story tells us that we must do what we say and what we do must bear fruit. Integrity is the basic principle of life and the lifeline of friendship between friends. Zengzi fulfilled the promise he made to his children with practical actions and set an example of integrity for his children. He taught his children to be honest and truthful, and also set a correct benchmark for the growing teenagers and children, allowing us to move in the right direction of integrity.
