I don't know that particular place; but as an old China hand I can tell you that as a rule these kindergartens in China are operated by idiots with an intelligence level lower than the kids they are looking after. They are operated by private business people trying to make a quick buck, so don't expect any pedagogical standards, rude and illegal treatment in contract matters like not being paid in full and on time. Private kindergartens in China are a big avoid, and if you really felt called to working with young learners, you should try real Primary School run publicly instead.

Kindergartens in China like the one you have mentioned are shitholes in general that no decent teacher/nurse should ever work for!
