Bao Yixin has not been playing WD lately, focusing on XD. My guess is she won't be going to Rio for WD, but most likely going to Rio for XD. Tang Yuanting and Ma Jin looks like a good pair. But not particularly dominant like Wang Xiaoli and Yu Yang. If they reach that stage, this pair very likely will go Rio. Another pair that I like Wang Xiaoli and Zhao Yunlei. If Zhao can handle the double duty, this could be one possible pair. And also if Wang Xiaoli's performance is up to par during this cycle. Someone else could be Zhong Qianxin, but she needs a good partner. But for now, I don't see her having any chance at Rio at all. Don't think Tang Jinhua and Tian Qing will have a shot a Rio. Perhaps like the Tian Qing/Zhao Yunlei pairing, they could likely just be an experienced pair who goes for tournaments to get medals and help the team to secure gold medals and trophies... but not a sure win pairing for major individual events like the Olympics. In other words, just a strong and steady backup pair in case other pairings falter (like Wang Xiaoli/Yu Yang in the last Olympics...).
