“When Wang asked the referee to have the sweat on the floor wiped clean, he refused, and that was why she slipped and injured herself,” Li said to Xinhua news agency.

“It was ridiculous. A player who takes time to wipe off the sweat on the face could be suspected of intentionally delaying the match. But when there is sweat on the floor, the referee should have it wiped off or allow the player to clean the floor.”
