BEIJING - China's five-time Olympic champion diver Chen Ruolin has retired aged just 23 due to a neck injury, bringing one of the most spectacular careers to an early halt. Chen took home five golds in three Olympics, most recently winning the women's 10 metre synchronised platform in Rio in August. She announced her retirement in a post on her verified Weibo social media account. "When this day arrived I never thought it would be so tranquil," she wrote, adding that complications from a neck injury "make it impossible to continue". "So, I choose to retire. Thanks everyone for your care and support." Chen, one of only three Chinese athletes to win five Olympic golds, began diving aged four, joined the national team at 11, and made her first Olympic appearance at Beijing 2008 at 15.
