Did Dai Yun give an example during the period of Daming Chenghua?

Born 2 1 century before the Republic of China.

He died in 5 1 year.

This man who worked hard for academic and cultural progress, freedom of thought and speech, national honor and human happiness is now at rest here.

We believe that the ruins will eventually disappear and the valley will eventually mutate, but the light given to the world by this philosopher in the grave will last forever.
