19491February 12 with the consent of Tang Yongtong, Chairman of the School Committee of Peking University, and Zheng Tianting, Secretary of the School Committee, Wang Zisong drafted a letter to President Mao Zedong, asking Liu Chunnian to copy it in regular script and send it to Chairman Mao's office in Zhongnanhai. Chairman Mao was asked to write the name of Peking University on the anniversary of the 5 1 anniversary (65438+ 17 February, the first anniversary after liberation) for making a new school emblem. The attachment of the letter is a piece of paper, on which is a rectangular box painted by Liu Chun New Year. It is 1 1 cm long and 3. 1 cm wide. When Chairman Mao wrote the name of the school, the box was marked "Peking University" for reference. 1950 March 17, the Secretariat of the CPC Central Committee sent the inscription of Chairman Mao as the emblem of Peking University in an envelope, with a postscript: "Please check it."

The tall lintel of the West Gate of Tsinghua is engraved with the four free and easy characters "Tsinghua University" inscribed by the founding leader Mao Zedong. 1June, 950, busy Chairman Mao wrote six "Tsinghua University" at the request of teachers and students in Tsinghua. As a master of calligraphy, he also modestly pointed out that "the right side of cursive script seems better". Since then, the school emblem inscribed by Chairman Mao has been accompanied by every teacher and student in Tsinghua.
