How long can ZhangJike persist in not retiring, and will he enter the entertainment circle after retirement?

There is no doubt that ZhangJike's performance in the national team is one of the best, but at the same time, his body is also overloaded. I remember all of us were really worried about him at the Rio Olympics! And ZhangJike already had the idea of retiring. During the Olympic Games, when he was broadcast live by a live broadcast software, he remembered that he wanted to retire after the Olympic Games. Maybe it's a joke, but the idea of retirement must be on his agenda. But without warning, he got angry because of the "sleepless" stalk. At this time, even if he wants to retire, he can't, because the table tennis team needs him, and so does the table tennis team's "three innovations" work. Of course, he will not hesitate to stay.

It's really hard to say whether ZhangJike will stick to the Tokyo Olympics. From an outsider's point of view, I think he should not insist, on the one hand, because his body may not allow him to train with such high intensity, on the other hand, because the competition for talents in the table tennis team is too great; But from the perspective of a fan of Ji Ke, I still hope that Ji may persist until the 2020 Tokyo Olympic Games and bloom as a "Tibetan Mastiff" in Tokyo.

As for whether ZhangJike will enter the entertainment circle after retiring, this ZhangJike once talked about this topic in an interview. At that time, he was really excited, so I didn't think Ji Ke would enter the entertainment circle, but you never know. Do you think you should enter the entertainment circle after science?
