As Confucius' favorite student, why was Luz finally chopped into a paste?

There are many students of Confucius, not to mention that after Confucianism became the mainstream, almost all scholars were disciples of Confucianism, including us now. Even so, many students followed Confucius, and one of them dared to "kill" Confucius directly, and he also assumed the responsibility of Confucius' bodyguard. However, such a student who was deeply loved by Confucius was finally chopped into pieces. Because Lutz is brave, loyal and unyielding, it is precisely because of his character that he was chopped into a paste in the war. At the same time, as Confucius' favorite student, Luz always remembers Confucius' teachings. Even in the face of danger, he kept his face straight and dressed modestly.

In Confucius' view, although Lutz studied with him for a long time, in fact, Lutz only learned some fur of etiquette and music. The core of rites and music has not been internalized by the quilt. Lutz is just an ordinary man dressed as a gentleman. Such a savage, after being an official, is easily incompatible with officialdom. Lutz died at the tassel simply because he was plunged into chaos while defending the country. In the battle, Luz lost his hat. He stopped fighting and put it on. The enemy took the opportunity to chop him to death. When Wei Zhuanggong became a monarch, he made Luz's body into a paste and presented it to Confucius. Soon, Confucius died of grief. Even if you violate the teacher's will and offend powerful people, you should stick to your own point of view and eventually die in your own music system. He went back to Beijing to stop Kui Ming from violating the etiquette system and dying for gentleman etiquette and musicians. His death seems to be the result of "pedant" and stubborn struggle, but for Lutz, it is his persistence in his ideal.
