This is a tough event, with players facing nine intense matches over three days.
It is all part of a hectic schedule for GB's top players. As well as the regular training in China, Knight commutes twice a week for club games in France, while Drinkhall plays in Germany.
It's the end of day two and Drinkhall lies second after five wins and a disappointing loss to current leader Thomas Tregler from the Czech Republic. Knight struggles, with just two wins in six games.
It's going to be a tense finale and Drinkhall and Knight reveal their thoughts to Olympic Dreams.
