OK from fans perspective, since fans always wish their favorite team to have the best players and to win every games. But what about the perceptive of parents who care the future of their child? What assurance you can offer to them? How are you going to convince them to let their talented kid to pursuit his or her sportive career when other options also offering to them?
Sacrifice for something better, Yes. But sacrifice for something inferior or for uncertainty, No.
Both players and parents already know they will have to sacrifice to become an athlete. That is already a given. What makes Yang Fangxu's situation any different? Nobody forced her to become an athlete. In the end it's still up to the parents and the children can quit if they don't like it. If there are better options, they will take them.
Nobody will know who Hui Ruoqi will be if she were a regular person. Now she is famous, and have opportunities in both sports world and entertainment industry. Yang Fangxu is very fortunate to have been treated so well all these years with her injuries. The spots she plays is weak so she is lucky in that as well. Not so much for Yang Junjing, who got injured playing a meaningless tournament, and missed out on an Olympic Gold. Her MB position has too many replacements so she is pretty much done.
Back in the old days, athletes just played to make a meal. Now with economy booming, becoming world champions and Olympics champions mean instant millionaire. This era, athletes have more opportunities for education, jobs, etc. What more could you ask for? Yang Fangxu is already getting the special treatment. What more can be done for her if she can't even play? No other country would do that for an athlete. At least I have not seen it. So I can't see in any way Yang Fangxu's situation would tarnish Chinese Women's Volleyball reputation.
