No,the filth and dirtiness has made me even more conscious about cleanliness. I simply refuse to accept the untidiness here. When I step into my apartment, I want to feel that at least there's some sanity. I don't think I can get that if I allow it otherwise. 

As louischuahm. I probably used to be a bit of a messy person, now I will be very strict about keeping the home clean. When we have guests and they fail to fall within what I find acceptable (e.g. like dropping a piece of candy wrapping on the floor and not picking it up) I will demonstrate in front of them how to do that. The MIL for some reason doesn't find water and tea on the floor to be a problem, I kind of don't either, but I will always wipe up after her, while she watches. 

When out. I wouldn't say standards have dropped, but perhaps they've changed. 

I became maniac about keeping my flat clean in China. This is the only place where I can escape the things that irk me here : low hygiene standard, noise, etc.

Also, China made me long for town-level politics and city councils. Where elected representative have to front their town folks and defend their projects, where there are debates about your future daily life, etc. I used to despise those things, now, I *DREAM* of it.

With working at the training school, caring for my baby & extra teaching on the weekends in the county, and studying to become a freelancer, I'll be lucky if I have time to cook, let alone clean. I won't pretend to be a neurotic housekeeper, and I won't pretend to be ashamed of it. Yup: I'm one of *those* people - don't forget to roll your eyes.
As for the pollution: My floors get covered in dust far more easily than back home, and white floor tiles just make it more visible. I watch to see when my neighbours clean their part of the hallway, then I do my share, and my apartment floor while i'm at it. With a different mop, of course.

Sure, the main ones are care for hygiene, service expectance, politeness from people around in crowded places specially when queing up, etc.

When it comes to cleanliness etc, I am the same now as before I come here.

The area I live in is actually clean and tidy. But when I do encounter mess I don't notice it as much as I used to.

My "comfort zone"  has certainly changed a lot since I landed on these shores.

I moved here straight after uni, my flat is a lot cleaner than it was back home. My British politeness has definitely taken a back seat to blunted abruptness though.

My standards of what I deemed "acceptable" immediately dropped when I walked into my apartment. I would've never accepted an apartment in the condition mine was in, had I been in the states. It took me 3 days to get it spotless. I'm one of those guys who likes everything to shine and smell like pinesol and fresh linen at all times. Out in public I am the same. I refuse to lower my social standards just because the people in China lack my idea of social etiquette. I will continue to always look for a garbage can to throw things away. I will continue to wait my turn in line, even if someone jumps me in front of me, and I won't say anything. I will continue to keep my teeth clean, even though Chinese people laugh and ask me why they are so white. China has taken a lot from me in terms of air quality, water quality, Trader Joe's, Gruyere cheese and Napa Valley wine. But I refuse to let it take my sanity or my standards, nope, not going to happen.

I am shameless and have zero standards, so no.

My standards have lowered in every aspect of life, aside from my flat.  I only rent brand new apartments that haven't been soiled yet.  I think it's totally worth it.  My place is the only sanctuary I have, and I refuse to live in filth.

I've accepted nothingness as my norm.  I used to live a very busy life, what with family, work, sport, drinking, punting, etc...  In China I have adapted to nothingness.

If not for my lovely bride I would be searching for one of Hulk's bullets to the head.
