National Youth Day, which fell on Sunday, May 4, this year, is a commemoration unique to the country that historians say celebrates some of the ideals that formed modern China. The significance of Youth Day was underscored on Sunday by President Xi Jinping’s visit to Peking University Citizens and leaders of China are well aware of the importance of Youth Day, but here are some facts that others might not know.

Why Peking University?

Peking University was a launching pad for the May 4th Movement, an anti-imperialist, anti-feudal, political and cultural campaign led by students in 1919.

At that time, the university was a cradle for new ideas and its students were the main force in the movement.

The university provided fertile soil for young pioneers to spread the new concepts. Meanwhile, the movement pushed forward educational reform at the institution. Now, the university is understood as a witness to history.

To remember the May 4th Movement and inform young people, the university now holds activities each year, including inviting young leaders to give speeches, presenting flowers for young pioneers and organizing singing competitions.

Peking University students also travel to other provinces or invite other colleges to visit its campus on Youth Day, aiming to inspire more people’s patriotic enthusiasm and remembrance of Chinese history.
