Fitness is the key. You need to have strokes and stamina and agility; you need to exercise really well. On-court and off-court are equally important.
健身是关键. 您需要中风，耐力和敏捷； 你需要很好地锻炼. 场上和场外同等重要.
Life has changed both on and off the court after the Rio Olympics medal. I have a lot of confidence on the court now and feel anything is possible. I also feel that I have improved my game. Off the court, I do get recognised more now.
