Hello yanagi,
I've just checked that School but sorrowly its in Chinese so I can't tell you anything about that.
Me and my wife and daughter will probably arrive at the end of the year in Hefei for a 3 year stay.
We also let my company check for appropriate Kindergartens.
We actually only found two, Kid Kastle Kindergarten und French Annexy Kindergarten, both having native English speakers as teachers and also giving lessons in English.
We prefer the Kid Kastle Kindergarten which is quite new and also the care teachers speak English.
Cost would be 8k / Semester.
I will let my company check on the one you named if they can find out more.
You can also wright me a PN.
Greetings,
David
