Mu Zi did really well in previous "Road to WTTC" trails. For example, in 2011, she was the champion of "Road to Rotterdam", but she failed to make the single's match. Because the rule at that time was awful. The winner of "Road to Rotterdam" only guarantees a spot in the WTTC squad. You are not sure to play in the singles. So she paired Hao Shuai in the mixed double match and got her second sliver medal in mixed double.
For this time, the rule is clear that the winner will participate in the single's match. So I'm sure that Liu Guoliang will let her go unless she is injured during that time.
so how many players out of the 6 players will play in single match?
