This is endemic in China
One time my wife's granny was staying with us. I came through the livingroom one day to see her nonchalantly thrusting an index finger up a nostril. My presence didn't deter her - there was work to do.

Double standards
Yeah, I lived in a shared house in my last year at uni with 2 chinese fellas. They used to cough up phlegm and spit it in the kitchen sink (great when you're about to wash up), sit in front of the TV picking noses, always ate with their mouths open, shovelling in food with chopsticks and slurping away... and the mess they left in the bathrooms...

Then one day I was sat in the lounge with nail clippers and went to cut my finger & toe nails. They were shouting back and forth at each other in Chinese, glaring at me and getting increasingly livid in their own language, then one of them launched towards me like he was gonna knock me out. The other one had to hold him back, told me to stop doing this disgusting thing in public, and how I'd insulted them both.

Pair of chingy mentalists!

it sticks around in chinese families, too
even ones that haven't lived in china for decades.
