Three teams achieved a perfect win record on day one of the World Rugby Women's Sevens Series qualifier in Hong Kong as the quarter-finals were confirmed. 

Kenya, China and Belgium all notched up three wins apiece at a sun drenched So Kon Po stadium on Hong Kong island. The quarter-finals are as follows (all times in GMT+8):

China v Papua New Guinea  - 10:30 
Belgium v Brazil - 10:52
Wales v South Africa - 11:14
Kenya v Argentina - 11:56

Kenya started off the day in a crunch match against Papua New Guinea, coming out as 17-5 winners. A 40-0 win over Mexico and tight 24-12 win over South Africa, which had one of the tries of the day from Sinaida Omondi, secured them top position in Pool A with a points difference of +64. 

China's path to the top of Pool B required them to dig deep against Kazakhstan in their opening game, taking a 14-7 win with Gao Yueying and Liu Xiaoqian both scoring clinical tries. Hosts Hong Kong were up next, with a buoyant local crowd creating a wave of noise around the ground, but China's attacking prowess shone bright in the first half with two tries, followed up quickly in the second half by another from Liu Xiaoqian to give them an eventual 19-7 victory. A dominant 31-5 win over Brazil secured them their perfect day one record.

Belgium conceded just five points all day, starting out with a 12-0 win over Argentina. They added a 19-0 victory over Poland in the early afternoon and finished the day off with a closer 12-5 win over Wales. 

Day two of competition will kick off at 10:30 local time and will be streamed on and
