Two Chongqing university students have used fallen ginkgo leaves to help preserve precious memories of their campus days.

The architecture department students drew pictures of their school on the golden leaves. The drawings include many landmark images of the university, like the gate, the main teaching building, the clock tower and the black swans that are found there.

When asked how they came up with the idea, one of the students, Zhu Huanhuan, says: "It's my last year in Chongqing. During the past five years, I have experienced the golden ginkgo seasons many times. It's so unforgettable. So I want to use my own drawing to keep precious memories of my university in mind."
