Cultural Differences

I've been making a list of cultural differences that we have noticed in our short time in China, and the list has gotten long enough for me to write about it. I am hoping to use this list to teach my students about some differences between Americans and Chinese and how they can be better prepared for interacting with foreigners, especially Americans. So, here is our list thus far:

1) Cutting- as in cutting in line: B/c the bus system here is incredibly cheap, and pretty convenient we have been using it a lot to get downtown from where we live. There are usually lines at certain stops where you can wait just to have a seat, rather than stand for 30 minutes. And apparently it's okay to just walk past everyone right to the front. I'm going to tell my students that if you do this in the U.S. not only will you get yelled at by some grouchy old man or women, but you may just get punched in the mouth.
2) Nose picking- Now, I know that everyone participates in this ancient pastime across all cultures. BUT.... unless you are under 6 years old you are typically as discreet about this as possible. Meaning, you DO NOT jam your finger up your nose, dig around a bit, examine the treasure, and yes.......do the deed, when there are 1.2 million people standing around you. At first we all thought this was just some guy who didn't care, but a month in China has taught us that this behavior is not uncommon. Mostly men though, of course.
3) The BABY PANTS- you may have seen pics of the baby pants online, and I will try to post my own pic soon. Basically, the young children here wear pants with a slit down the middle so they can pretty much take care of business at anytime in almost any place. Sometimes a parent will scoop their child up and run them to the nearest trash can, but there isn't always time for this.. Sure the kids are cute. But this has to stop.
4) Smoking...Smoking..and more smoking...- I know that we hail from California and there are few places left where people can indulge in their lung cancerous behavior. which is great! but in China this form of population control is rampant. Cigarettes are practically free here too, maybe 50 cents a pack U.S.$, so that isn't helping. And they smoke everywhere, literally. Restaurants, school, theme parks, taxis, zoos, pre-schools, you can smoke them on a train, you can smoke them in the rain, you can smoke them in my face, you can smoke them ANYPLACE!!!! you smoke your cigs all day, right until you're in your grave.....
anyway, it's pretty gross, and requires constant clothes washing and breath holding.. hopefully they will figure it out soon. but i doubt it.

i think that i will save the rest for another time.
