Career
He is the Taiwanese record holder for the event with a personal best of 82.11 m (269 ft 41⁄2 in). Huang initially played association football as a child, but after the school team was disbanded he took up athletics around the age of 14. He continued with both sport and study, beginning a degree at Fu Jen Catholic University.
He had his first international success in the youth category of the sport: entering the 2009 World Youth Championships in Athletics as a rank outsider, he surprised by topping the qualification with a throw of 74.75 m (245 ft 23⁄4 in) – a two-metre improvement on his lifetime best at that point.
He reached the 74-metre mark in the final and declared himself shocked to have claimed the gold medal over Killian Durechou of France. He stepped up to the junior category the following year and managed a bronze medal at the 2010 Asian Junior Athletics Championships, behind his compatriot Cheng Chao-Tsun.
He was unable to repeat global success at the 2010 World Junior Championships in Athletics, finishing the qualification round without a single valid mark. Huang had a consistent level of improvement in his first three years throwing the senior weight javelin: in 2010 he threw 72.74 m (238 ft 73⁄4 in), then had a best of 73.63 m (241 ft 63⁄4 in) in 2011, and 76.54 m (251 ft 11⁄4 in) in 2012.
He represented his nation at the 2013 Summer Universiade, placing 13th in the final.
He threw beyond eighty metres for the first time at the 2013 East Asian Games and was rewarded with a Taiwanese national record of 82.11 m (269 ft 41⁄2 in) and a silver medal (losing only to China"s Zhao Qinggang, some seven years his senior). He ranked third among Asian throwers that year, behind Zhao and Ivan Zaytsev. He threw nearly seven metres less at the 2014 Asian Games and finished down in ninth as a result.
He was strong in the early season again in 2015, setting a mark of 81.48 m (267 ft 33⁄4 in) in March in Taipei City.
A throw of 79.74 m (261 ft 71⁄4 in) proved sufficient to hold off both Uzbek Bobur Shokirjonov and Japan"s Yukifumi Murakami at the 2015 Asian Athletics Championships, earning Huang his first major senior title.
