Seeing how zhang Nan is playing this XD match, I suspect he is ambitious and wants to do a double doubles here, two gold medals.
ZSW's gameplan is really weak in the, lifting at the net when LYH is there. I guess he is choking again.
FYI, commentators, the reason why Zhang Nan/Li Yinhui are ranked so low, WR16, is because they have been split as Zhang Jun disallows any CHN doubles player to do double duty for the Olympics and Zhang Nan is tasked to concentrate on MD alone, so this WC will be the last time we see them play as a pair.
