Under the format, individual matches last for three games resulted in either a 3-0 or 2-1 scoreline. Team matches are played to a result where the first team to accumulate eight games wins.

Following an 8-0 victory over Sweden on Monday, hosts China continued their momentum to dispatch Hong Kong, China 8-0 in its first match of the day.

The winner and runner-up of each of four groups advance to the second stage.

Sweden regrouped from its opening loss to China, outplaying Puerto Rico 8-3 and Hong Kong, China 8-0, to advance as the runner-up in Group 1.

Germany and Slovakia progressed from Group 2. In Group 3, Japan and France finished top two to qualify. South Korea and Chinese Taipei advanced to the second stage as top two sides in Group 4.
