Terrible 3rd game performance by Zheng Bo. He really lost it. As the senior partner, it should be him to help his inexperienced partner. It's a lesson how NOT to play doubles. If he goes back many years ago to the Chinese National Games in Guangzhou, he was playing mixed with Huang Sui. That time Huang Sui was giving him the black face. He knows how terrible it feels like to be on the receiving end. (I was there watching).
