Youth is beautiful; it can mean different things to different people. For 27-year-old Wei Xiaohui, youth is like the spiral staircase "springing" upwards - growing vigorous, never frustrated. Wei explored 28 campuses of 15 colleges in Nanjing in 2016, presenting us a collection of staircase-themed photos memorizing the campus life. "Young people can find hope in these images. I hope they can overcome every challenge in their lives as each challenge can be an opportunity to move ahead," Wei said.
