Career
She holds a discus personal best of 67.86 m (222 ft 71⁄2 in) and a shot put best of 16.59 m (54 ft 5 in). Gu began to make her first impact at the age of sixteen, when she took the discus title at the 2009 Australian Youth Olympic Festival. She threw beyond fifty metres in the discus for the first time that year.
International medals followed at the 2010 Asian Junior Athletics Championships where she claimed a shot put/discus double for China.
She took the silver medal in the shot put later that year at the Summer Youth Olympics. She was also runner-up in the discus competition and ended that tournament with improved bests of 16.59 m (54 ft 5 in) and 56.12 m (184 ft 11⁄4 in) in the throws.
Both these marks ranked her in the top five juniors globally that year. She marked herself as the best junior discus thrower in the country in 2012 by winning the Chinese junior championships with a big personal best of 60.59 m (198 ft 91⁄4 in).
She was far off this form at the 2012 World Junior Championships in Athletics and her best of nearly five metres less was only enough for fifth.
Gu, dropping the shot put to focus on discus throwing instead, placed herself among the senior elite in the 2013 season. She began with a new best of 60.93 m (199 ft 103⁄4 in) on the Chinese Athletics Grand Prix circuit. She travelled to compete in Germany in May and the 20-year-old surprised with a large throw of 67.86 m (222 ft 71⁄2 in), raising her to second on the seasonal lists behind the dominant Sandra Perković.
She eanred her first senior selection for China as a result, but at the 2013 World Championships in Athletics she failed to register a valid mark and dropped out at the qualifying stage.
She had a quiet 2014, her best being a throw of 60.78 m (199 ft 43⁄4 in) in Jinan. Shot put – 16.59 m (54 ft 5 in) (2011)
Discus throw – 67.86 m (222 ft 71⁄2 in) (2013)
Shot put (indoor) – 16.34 m (53 ft 71⁄4 in) (2012).
