World and Olympic badminton champion Lin Dan added a first Super Series Finals title to his trophy haul on Sunday with a 21-12, 21-16 success over Chinese compatriot Chen Long.
The women's title went to China's World No 1 Wang Yihan who came from behind to beat India's Commonwealth champion Saina Newhal 18-21, 21-13, 21-13.
China also lifted the women's doubles and mixed doubles crowns but Danish men's duo Mathias Boe and Carsten Mogensen beat Chai Biao and Guo Zhendong 25-23, 21-7 to prevent a clean-sweep.
The season-ending $500,000 tournament was held in the Chinese city of Liuzhou.
