I am not "blowing water". It is real case. I have about 10 friends living in HK island and NONE of them have heard of CKY, TSL, APS, KTS. 1-2 of them has heard of SFA.
It is not these parents are naive, but, in fact, these schools are not famous enough than those top ones.
Similarly, my HK friends only know very few Kowloon kindergartens, such as St Catherine's and Kentville. They have never heard of those like HK Preschool, 劍鳴, 金巴倫, York, 創價, etc.
