It should be "the idea of ??independent spiritual freedom"
On the second anniversary of the death of Mr. Wang Guowei, the tutor of the Tsinghua Institute of Chinese Studies, teachers and students of the Institute set up a monument at the foot of the hill north of the second school gate. Chen Yinke Mr. Wang wrote the inscription. This is the most widely circulated sentence, which has transformed into the spiritual character of generations of Tsinghua scholars, but now it is gone!
Inscription on Wang Guantang's Monument at Tsinghua University
The study and scholarship of scholars will be based on freeing one's mind from the shackles of worldly truth, and the truth will be carried forward. Without freedom of thought, one would rather die; how can one even dare to hope for the essence of the benevolent saints of ancient and modern times who died together. Mr. Yi sees his independent and free will through death, and it is not about the grievances and grievances of one person or the rise and fall of a surname. It expresses the wonders of the philosopher and expresses the confusion of the true master. Since the future life is unknown, Mr.'s writings may sometimes be incomplete. Mr.'s teachings may sometimes be debatable. Only this independent spirit and free thoughts have lasted for thousands of generations, and are as long as the sky and the earth, and they have three lights and are eternal.
