I don't while Hao Shuai, might have been "smiling" I think it was more just exasperation/almost embarrassment, that he kept on missing those lobs. When ever he misses those shots that an elite player should generally make, he tends to have a half smiling, half perplexed, confused look on his head, as if he is scratching his head in confusion. It just seems like he doesn't have the right attitude or mentality to become an elite player.
