408182: GYM103048 C Countdown

On the evening of October 18 in 2020, the ceremony to launch the countdown to the 70th anniversary of East China Normal University was held on Zhongbei campus. The ceremony unveiled the logo for the celebration of the upcoming 70th anniversary of ECNU.

Designed by the School of Design, the logo, which is inspired by the pillars in front of the Qun Xian Tang, other landmark historic buildings of ECNU, and the architectural emblazonry and mortarboard sculpture in front of Li Ke San Guan, implies that ECNU, in its 69 years of development, has cultivated a galaxy of talents for the country.
