My Thai son suggested we move (son, his Thai wife, kids and me) from Bkk 6 months before his first child was going to finish kinder in Bkk.
We had, as a family done week-end/week visits to CM many times before and always came back to CM for more.
Son suggested full move to CM because he wanted his child (and more planned) to grow up in the CM 'culture' rather than Bkk (big, fast not all that friendly).
His take was CM people are more friendly and more more helpful, more supporting/caring, better circumstances for the kids to be imersed in.
Son and family searched CM for school and found several, son and his wife readily found good work and since moving here have established 2 successful businesses, and found good reliable trustworthy friends. Son's eldest child now at CM uni and all happy with the quality of her study.
Before we moved son and whole family searches CM for good housing and bought land and house in a new moo bahn just off the superhighway in the Don Chan area. Lucky got in before several very large rises in land prices in CM. Now have great 5 bed house, nice family/kid friendly village, upkeep excellent.
Old friends often visit from Bkk, want to also move to CM but land/housing prices 'blocking' their move.
Yes CM has some pollution / smoke problems but hoping MF will make some progress on this point.
Our family move to CM highly successful.
