CHENGDU - Title favorites Qingdao Renzhou faced little challenge at Thursday's Chinese Badminton Super League as they defeated Xiamen Tefang 4-1 to secure their sixth straight victory of the campaign.

Qingdao stormed to a 4-0 lead after they took victories in mixed doubles, men's singles, women's doubles and women's singles. However, men's doubles young pair Guo Ruohan and Shang Yichen defended some honor for Xiamen as they overcame a one game deficit to beat world champion Liu Yuchen and his partner Guo Junhao 9-11, 11-8, 11-9, 11-9 in the final dual.

The win meant Qingdao continue to lead the overall standings, although second-placed Ruichang Biyuan also cruised to a victory, beating second from the bottom team Anhui Souyu 4-1 later in the day.

In the other two clashes of the day, Hunan Hualai beat Zhejiang Energy to remain in third place, while Shenzhen Nankeda whitewashed Jiangsu in 5-0 to clinch their second win of the season.?
