Bobby, aka Lin Ziguan, is a passionate young climber in Wenzhou City, east China's Zhejiang Province. He first came across the sport when his parents took him to an indoor climbing facility at a local shopping mall for fun, and it was a case of love at first sight. To further fuel his passion, Bobby's father refurnished a room at home and turned it into a private rock-climbing gym. While many students find themselves "climbing the walls" with frustration on weeknights and grumbling at their homework, Bobby spends most of his free time clambering around the surfaces of his bedroom as he aspires to become a celebrated outdoor rock climber one day.
