Letter to Xiong Zirong
(April 14, 1950)

Brother Zirong:
Both your letters and the manuscript have been received. That your research has yielded insights and your thinking has progressed is gratifying and praiseworthy. When you come to Beijing in May, we can talk face to face. This is my reply.
Respectfully wishing you success in education!
Mao Zedong
