Which parent-child swimming pool has better quality?

depending on which city it is, it's not long since I first came into contact with Erbao. When I first started to contact it, we went to several places to experience it, judging from the overall environment, scale and teaching quality. You Faner from Beijing is ok in this respect, their courses are reasonable, the swimming pool environment is good and the scale is large. The coach is also serious about the baby. The charge is reasonable.
