Sun Yingsha used to use the same racket as ZhangJike and Fan Zhendong. Butterfly's exterior, seven-layer substrate, fiber structure. This kind of floor is characterized by its high speed, which has a good advantage in the middle stage and near stage, but the strength at the bottom is slightly insufficient, especially the forehand. After Sun Yingsha changed to Dragon 5. Just play steadily. Then when defense is transformed into strategy, forehand strength and arc will be improved to a certain extent.
