Powerhouses Qingdao Renzhou and Ruichang Biyuan both clinched victories at Friday's China Badminton Super League, remaining in first and second place respectively.

Qingdao edged defending champion Zhejiang Nengyuan 3-2, as Zheng Siwei/Liu Yuchen, Wang Zhiyi and Wang Yilv/Huang Dongping all took straight sets in the men's doubles, women's singles and mixed doubles respectively, sealing the victory for the team after the first three matches.

"It was not a hard game, and I felt good to partner with Wang again. We are very familiar with each other and we cooperate really well," said Huang.

Zhejiang then defended some honor with Huang Yuxiang overcoming Tan Zhendong 14-15, 11-6, 11-7, 11-6 in the men's singles, and Ni Bowen/Lv Rouhao beat Zhang Xinran/Chen Zirui 11-5, 11-2, 11-5 in the women's doubles.

Ruichang defeated Hunan Hualai 4-1 to continue sitting second, leaving their opponents in third place.

"I feel satisfied with my performance after the first seven rounds. I tried my best to earn points for my team in every game. As young players, we should seize the opportunities to improve ourselves through such games," said Li Shipei, who rallied from two sets down to win in the men's singles, securing the victory for Ruichang.

In the other two games of the day, Shenzhen Nankeda overwhelmed Anhui Souyu 5-0, while Jiangsu Weikeduo lost to Xiamen Tefang 3-2, still striving for a win this season. Enditem
