Hong Kong badminton player Angus Ng on Monday acknowledged he was unable to qualify for this year's Paris Olympics, adding he was thankful for the support he had received over the years.

Ng, 29, was trying to make his third Olympic Games, having taken part in the men's singles competition in the past two tournaments in Tokyo and Rio de Janeiro.

In a social media post, he said he took part in many qualifying tournaments and had tried to overcome many challenges on the road to Paris.

"Sometimes in life, you don't get rewarded correspondingly even though you've tried your best. Perhaps it is what it is in life," Ng wrote, while apologising for disappointing his "true fans".

But not only did Ng thank his family, friends and fans, he was also thankful for his "haters" for toughening him up.

Ng said "their mean comments", when he didn't play well, helped his sporting career and gave him resilience in life.

The player, who once ranked number six in the world, also said making the Olympics wasn't his only goal, and he would spend the rest of his career doing his best to brush up his resume.

Ng was caught up in a jersey controversy in Tokyo three years ago when some criticised him for wearing black. He ended up changing into new attire, and was knocked out in the group stages.
