Hi OP - I am a short pips chopper who trains with Li Jian and wanted to offer my testimonial / a few notes, because I found this post to be somewhat alarming at what likely is an important stage in your daughter's athletic development. I'm in part posting all this because I am fairly sure I've seen you and your daughter at training and as such you are part of our community.
For context, I started table tennis 10 months ago (rated at 700 in my first tournament), and have progressed up to a 1900 level under Jian's guidance and have a decent chance at breaking 2000 in under a year of playing. I can assure you with regards to short pips defence that two things are true:
1. As a player, Jian would be above 2500 using short pips tomorrow with no training (I have played against him with them on, he openly admits to chopping better with them than long pips but cannot adjust to minor tempo differences versus his normal game).
2. As a coach, he almost certainly knows more than any short pips chopper you will meet about development of this type of player including most at the professional level - this is likely because he has direct interaction with + access to the best players in the world using this style and talks with them often (e.g. Hou Yingchao). He not only understands the techniques for / nuances of the most difficult shots with the rubber, but also the expected sequences stemming from those shots and the appropriate tempo/footwork. It bears highlighting that he was not only a Chinese provincial team player, but actually a provincial team coach and may actually be a stronger coach than player.
I am as such relatively stunned that you would be trying to find someone else when you have a coach who would be the envy of, for example, many top European and even native Asian juniors wanting to pursue this style.
More importantly - and I could be misinterpreting something you said, but this was what I took away from it - your daughter's rating/ranking at this age and trying to find various people who can give little tips to help her progress against 1500-2000 rated players is misguided and perhaps irrelevant. I think this is really important to understand and I'm speaking from experience here: since age 8, I was top 5-10 in the country in my age group up to u19 for a racket sport (not table tennis) and was fully recruited to a strong school for this sport, and watched many players succeed up to the professional level and also watched many fail to become professionals - including, ultimately, myself. There were two and only two large determining factors predictive of success at a very young age: a very strong base of technique and footwork, and continued passion + enthusiasm for the sport. Winning or finding ways to win does not matter at this age nearly as much as having a kid who learns the right way and most importantly enjoys table tennis and will continue to do so. I have seen so many "winners" at the age of 11 go by the wayside by age 16 because they neglected technical development in favor of finding little ways to win in ultimately insignificant junior tournaments. So please think to prioritize those two things above all when selecting a coach. That is a really high bar and a coach who is a peak 2200 or below player probably won't cut it.
I obviously respect if it's just the case that this particular coach is not the right fit for your daughter (e.g. communication differences, totally valid), but I wanted to outline the above principles so you don't waste your time going in an unproductive direction. As an aside, I am more than happy to hit with your daughter for a bit or talk to you in person (if you mention my rating and playstyle to Jian, he will know who you're talking about and reach out to me). All the best.
