Probably the fed thought themselves being far-sighted by channeling more support to the younger skater. After all, they have been supporting Zijun for so many years always trying to give her almost the best in the world and her result is still not fulfilling the fed's expectation.
Also, the fed's intention to give xiangnjng the spot in 2018 might just be a thought or still in debate among the management team. Zijun might have somehow felt that as she began to say this year quite a few times that she is already an old skater, there are so many talented young skaters, and implicitly ask her fans to cherish the time now when she is still competing. But that is just a feeling, until recently she returned to Beijing and probably somehow realized that the team might be really thinking something so she took an immediate and strong strike on the fed.
