Introduction to Chen Yonggui's former residence: Chen Yonggui's former residence is a typical Dazhai-style courtyard. The courtyard is not big and has exactly the same shape as the courtyard next to it. The couplets on both sides of the gate read "Plowing the clouds, hoeing the moon, and creating new things all my life." "Shennong's new road, he has been in politics for half his life and has been an honest and wise man." This is the best evaluation of Chen Yonggui.
