Learn from Confucius and Mencius, Li Du and China culture.
Yang Xiou, who worships Zhu, Yang Xiou, Zhao's imitation of Korean (Soviet) school, and Wu Zhangzhang's The Origin of National Essence.
Note: Zhu, Wang Yangming (Neo-Confucianism in Song and Ming Dynasties); Sean Song, Song Yu (poet of Zhang Guo), Yang Xiong (master of Han Fu); Ou Zhao, Ou Yangxun and Zhao Mengfu (calligraphers in Tang and Yuan Dynasties); Su Han, Han Yu and Su Shi (essayists in Tang and Song Dynasties); Zhang Wu, Wu Changshuo and Zhang Daqian (China modern painters). The "Du" in brackets in the upper couplet seems to have been missed by the questioner, so the lower couplet also corresponds to the "Su" in brackets.
I hope my answer will satisfy you.
