Ren Cancan
Ren Cancan is a female Chinese boxer who has won three world championships. She took up boxing in 2002 and won the silver medal in the 2012 Summer Olympics in London in the Women's Boxing – Flyweight Division as southpaw, she is also a bronze medalist of women's 51 kg title at 2016 Olympics in Rio de Janeiro, Brazil. She lost in both of her Olympic Games to the double-champion Nicola Adams.
Her official birthdate is January 26, 1988, as registered with the international boxing association, but she told Reuters in Chinese through a translator, that her actual birthdate is April 26, 1986. January 26, 1988 is nine months after April 26, 1987 of the prior year, and East Asian age reckoning often used conception date for girls in the past, but that does not explain the extra year discrepancy coming from the translator.
