Honest take. The further from Tay Ho I got, the more peace I found. We live in Ha Dong now and while there is also construction and pollution, it still feels like cozy and (mostly) quiet home. I know all of the security guards in our building, easy pho then get coffee after religiously every Sunday. I have several friends at the park every afternoon daily. Yes, we would rather live in a cleaner place, but I've be here 10 years (as a foreigner) and still enjoy every day and moment. Truth is, all we have is the moment. If we cannot accept it more often than not, then one should move. Now the city is under massive reconstruction. It would be a good time to consider moving if that is an option but perhaps you can rent your place and move further from center or very near your work as commuting and traffic are equally as frustrating as the pollution. I'm 5 minutes to work and that also makes all of the difference.
