London 2012 gold medallist Li Xuerui survived a scare before booking her spot in the quarter-finals of the Badminton World Federation (BWF) China Masters today.

The Olympic champion and top seed conceded the first game against Japan's Ayumi Mine before normal service resumed.

The Chinese eventually recorded a 21-23, 21-10, 21-8 win to advance from the second round in Changzhou.

It was a day of few surprises with Pusarla Venkata Sindhu, the Indian fourth seed, also reaching the last eight thanks to a 21-9, 21-7 success over Chinese Taipei's Yu Chien-hui.

China's former world junior champion Sun Yu, the fifth seed, also made it into the next round.

Yu, the Singapore Super Series runner-up this month, defeated Saena Kawakami of Japan 21-12, 21-15.

The 19-year-old He Bingjiao, another Chinese player who won two gold medals at the 2014 Summer Youth Olympics in Nanjing, is also through.

The sixth seed saw off Japan's Kaori Imabeppu 21-12, 21-16.

In the men's draw, there was further success for China's big names in round three at the Olympic Sports Center Xincheng Gymnasium.

Double Olympic gold medallist Lin Dan reached the last eight thanks to a 21-13, 21-17 success over Japan's Riichi Takeshita. 

The second seed will be joined in the quarter-finals by top seed and double world champion Chen Long, with his compatriot seeing off team-mate Shi Yuqi 21-16, 21-10.

The two big names remain on collision course and will meet in the final if everything stays to form.

India's seventh seed Prannoy Kumar knocked out Liew Daren of Malaysia, 21-10, 21-15.

Lee Dong-keun of South Korea, seeded eighth, needed three games to progress in his encounter.

He eventually got the better of Malaysia's Iskandar Zulkarnain Zainuddin, 18-21, 21-15, 21-4.
