I don't wish to sound rude but dental hygiene is non existent in China None of them have pearly white teeth , mark my words None of them . It's different shades of yellow and brown with the breath reeking of a septic tank most of the time . And it's not just the adults I've seen children as young as 2 years old with similar problems. Absolutely filthy guys with zero sense of hygiene altogether. And they're a developed country by our standards .Proof that money can't buy class , etiquette or hygiene.
I'd strongly recommend use of a face mask with a de odoriser attached if anyone here's pI anning a visit to China I used it in all my stay in southern China. When asked why , I claimed precaution against bird flu to the bemusement of the Chinese there . However poor we are we mustn't forget dignity and respect for the other person .
I can attest to this . Even upper economic class Chinese have teeth that are disgusting as hell. I have to make sure not to come in their line of breathing, so as to be saved from the foulest stench .its like they host a graveyard of fish in there or have gargled their mouths with bacterial vaginosis infected pussy ....
