What is Lu Xun's attitude towards traditional ethics?

I don't think it is extreme. He just criticized the numbness and cold-blooded state of China people at that time with an attitude of "anger without dispute". This feeling can be found in most of his works.

This is not extreme, but most of his subjects are for this reason. He is patriotic, and he wants to passion the feelings of patriots through words. At that time, the society was in turmoil, and he only targeted those insensitive China people. This is not a traditional culture.

In "From Baicaotang to San Tan Yin Yue", at least he didn't criticize private schools, but he missed them even more. He also mentioned that he had read Shan Hai Jing. This can be seen from Lu Xun's support for traditional culture. At least not targeted.
