Chen Long was emotional following the successful defence of his singles title at the World Badminton Championships on Sunday.
The top seed dispatched Lee Chong Wei for the fourth straight time, needing a touch over an hour to secure a 21-14, 21-17 win.
Following the final point, the Chinese national was reduced to tears on the court in Jakarta.
"Last year I also cried, but this year I maybe cried more," he said via a translator.
"This was a very difficult tournament to play. Every match was very difficult. Every opponent was very strong. I'm so happy to win this men's singles, not just for myself but the China team."
Meanwhile, Lee heaped praise on Chen for constantly adapting his play.
"Today he played so well," said the 32-year-old after the match.
"I tried to adapt and all the way he defended. I tried to play a rally and he ran with me."
