Pissing against the wall along streets is not a good habit at all but it's common everywhere in Viet Nam. This is a real shame for people who have to walk past these people and have to smell the very bad smell. There is a lack of public toilets in Vietnam and, when you use them, you have to pay and most people don't want to pay for that or can't afford to pay for that. It seems that we don't care about the hygiene or beauty of the country but the Vietnamese government needs to provide cleaner, cheaper facilities. There is supposed to be a fine for pissing in public but I've never seen the police do anything about it.
I'm not really sure what can we do to stop this kind of bad behavior?
