She has an elbow/forearm injury that keeps flaring up after months of non-invasive treatment, since the commencement of German Open. Unsure if the success of those treatments were partially marred by her (or coaches') insistence to continue training, hence those "clips" that you have seen. Rumour has it that she's been back at Guangdong for about a week or two now, presumably to seek further treatment or break away from training to speed up the healing process. Nevertheless, the players will all return to their own provincial teams soon and regroup in July.
Let's hope a year is good time to recover and gets some form in. LSW along with XX just prove to be perfect pairing in XD. Interesting to see how this plays out.
