As a 28-year-old from Shenzhen, Zhou Ziqian biked nearly 30,000 kilometers over 400 days. As he rode around China, Zhou promoted Universiade, China's collegiate-level athletics competition. On the way, he not only took pictures of 2,011 smiling people holding a UU, the Universiade mascot, but also met a lot of interesting people and had many fascinating encounters. Zhou says the trip changed the way he views life.
