The Chinese federation needs to heavily invest in Yan Han. He has so much going for himself as a skater, especially his skating skills. He has unbelievable potential, some of which are already tapped and shiny, but other bits need help. It would be a horrible waste if he doesn't get it. He needs more than just a few sessions with a good choreographer. What he needs is ongoing coaching on how to perform, how to move and how to listen to music. He also needs more exposure to a variety of performance arts. Throughout the years, the Chinese federation has squandered a lot of skaters who had so much going on technically but never got the help and inspiration in the performance department. Han can do better than most of them even without the help, but he'd do better with it and he deserves it.
What is weird is that out of all these Chinese skaters who are way below average in performance ability, you have Sui/Han who are exceptional not just in China but in the entire world. Whatever it is that made it work for them (unless it is totally innate) needs to be noted and made use of by the Chinese federation. Is it their choreographer, former ice dancer Wei Zhang? Ice dancing may actually be fertile ground for future choreographers and coaches for the Chinese skating program. It is a discipline that emphasizes performance and immersion in a vast variety of styles. Even if Chinese ice dancers aren't as competitive as their counterparts in other disciplines, they may have valuable skills to impart. And they can't confine this sharing to just pairs. There's plenty the single skaters can learn, too, if I'm right. Sic Wei Zhang on Yan Han. Heck, stick Yan Han with Sui/Han. He can pick up performance skills from them, and Sui Wenjing can pick up better skating skills from him.
