In Tibet

They are allowed 3 children that are provided education,
medical and food helps needs,
if they have a fourth, which is discouraged,
the only result is that the 4th child does not get state
aid. This does not mean a family cannot pay to get
the child education. It is just noT supplied for free.

what China does within China
concerning trying to keep population control
in a grossly over crowded country,
is far different from what they allow in Tibet.
