I know many kindergaten kids of SH from Kowloon or even NT. Kowloon is quite normal for primary school too. Principle just said too far is not ok when someone asked. For me I think kowloon is not TOO far. But really the concern is if you wish your child get up really early in the moring for school.
Yes normal case is like that. But I also consider if school starts too early if it is not close to home. Normally am session schools starts earlier than full day school. ^^
