I wouldn't bother too much with all those rumours. Boyang's been sent to Lori Nichols for two seasons now, and his placements this season (and their own 2022 hopes), should help them see light. It might be in shambles (maybe), but I doubt it's bad enough to scrape all their preparations for their own athletes -- seems conflicting to me.
Just needs more time with choreographers for this season, at least... But ideally a lot more than that. I'm not sure how much more his current coaches can help him, though they deserve the praise for instilling his jump technique. At least, I hope he gets sent for summer training with a coach, too. Teaching him how to do jumps with more difficult entries, and making sure that he doesn't jump so close to the boards, are things that coaches can change, so hope it's appropriately addressed. I just don't know how he'd balance this and the PCS part unless he goes to a coach in Canada for the summer (or maybe he'll bring his coaches along). I'm not sure how coaching in China works, or how skaters interact with their own feds, though.
