I do miss living in Hong Kong but also miss life in Singapore where my husband was transferred to after his ( now former) company changed their regional HO from HKG to SG. We basically had no choice.
One thing we do have better here in Sweden is the quality of housing. The rest, the jury is currently out on that one. Maybe our government gives too much freedom here as deaths from the COVID have risen even further to well above 3000 now. Much less pollution, yes. Quieter? Yes, but then again we live semi rural.
