In a way it is not a matter of confusion me, but maybe that it baffles me.  And it is mainly two things, one is their propensity to lie, for no apparent good reason, maybe just for the hell of it, or keep up in practice.

And the second one is their inclination to shoplift.  Since I became aware of it, and started paying attention while at stores, it is a wonder that many places are not already bankrupt.  Men placing things into their shoulder bags, or women into their purses seem to be a continuing occurence here.

And one last one, superstitions.  About three weeks ago I started to notice that the license plates on most cars I see on street and roads do not have a number 4 on it.  I started checking closely every license plate near me, and in maybe 25 days, I would say maybe as many as 100 different ones each day, I have seen only 5 cars with a number 4 on their license plates.  From 0 to 9 is 10 numbers, so roughly 10 % of cars in China should have a number 4 on their plates.  Yet, they do not.  Have you seen many license plates with a number 4 on it?.

I get the bus, five days a week, to the same stop. Every day, 80-90 per cent of the people on the bus get off at the same stop as me. Every day, 80 per cent of the people frantically shove each, all trying to get off, before the doors open. 

Do they not realise that everyone's getting off, shoving ain't gonna help? It actually takes longer because they're all tripping over each other!

When somebody does or says something wrong to another, they're completely casted away - forever.

It is difficult get used to those Chinese, who are spitting and littering  everywhere (regardless outside or in premises); to those, who would stand and talk hours in a doorway without paying any attention to people, who can't enter or go out, because of them; to those who will always push you in public transport and move you aside, while you are standing in a line in a canteen or in a supermarket, etc.

One time, when I was getting off the bus, a woman, who has just got on the bus, didn't give way. When I asked her to give way she said, that there was no need to get off at that moment and that I could get off at another bus stop. ))))))))))

However my close Chinese friends never act like this, I wish there were more Chinese like them:  with good educational and cultural background.      

The way the speak soooooo loudly!   Wow!   To me, that just makes them come across as savage. Does anyone else think that ?

I also found it so odd that they do not consume a beverage whilst dining. They tell me they 'drink soup'.   lol

Everything seems backwards sometimes. Like lefty loosy righty tighty is not true anymore. Now it's lefty tighty righty loosy. Especially true for opening and locking doors. Sometimes they do that for the escalator to where they have the wrong escalator going up and the escalator beside it going down. 

This society is completely backwards, from it's foundation to it's core to its head.  It affects everything that we take for granted back home.  The fact that I have to pass multiple instances of human excrement every day.... in the street, in flower planters... these people don't even respect the boundaries between where you live and where you sh!t.  Most animals even do that.  I often walk the street in disgust at what I see.  Don't they also see it?  Don't they also feel disgust and shame?

I am building a school.  Often I have to show the contractors how to do their own job.  Sometimes they call their boss and complain.  I absolutely cannot trust a worker without my supervision or he will do a lousy, tacky, sloppy job.  Their divisions of "skills" is without logic (Why is it your job to hang the drywall, but somebody else's job to fill the joints and finish it.?)   Why do manufacturers sell obviously defective products?  Boy, I'm on a roll today.  I hope this isn't a Bad China day.

I can't believe how blindly they believe what other people tell them, whether it's their parents, their teachers, or other authority figures. Sure, they are suspicious of the government. Maybe that is too obvious? But they'll believe TCM as if it's true? They don't do their research on anything, and if you try to prove it wrong, even with proof they may not believe you. Do they just not care or what? Giving IV drips, even to babies, because they have a cold? People complain that Chinese have no logic, but I think the truth is that they are lacking in knowledge. After all, if they knew that TCM doesn't work for certain things, if they knew that the IV drip can't heal a cold, would they go? No, they wouldn't want to waste their money.

The strong belief that everything is fine, harmonious and tolerant here.
The logic when driving. It baffles me every single day.
The extreme/childish stubbornness.
I often get told, all in one conversation, that my country is in deep crisis while China's economy is rock'n'rolling, and that westerners are rich. Again, baffling.

A few things that still confuse me to no end (and it happens everytime) is when people waiting to get in an elevator try to do so before letting those out first. Countless times, I've been in a jam-packed elevator, and sure enough, when the doors open, people start trying to push their way in, not even caring that there is no room because it is going to be full until people get out!!

Another thing that I will probably never get used to is the way people drive. There is no common sense, consideration for other drivers, or regards to traffic laws. In fact, the way most drivers operate does nothing but cause worse traffic and conditions.

And yes, as Jnusb416 stated, the whole "IV to cure a cold" routine. It's the first thing people do when they get a cold; head on down to the local clinic for an IV treatment. I would rather have the cold and eat lots of oranges!

Driving without paying attention to....anything.

And pushing the damn elevator buttons so many times.

The littering. Seeing people litter even though a bin is a few meters away gets me pissed. Its not that hard to put rubbish in the bin.

China should have a day when all the street cleaners have a day off so they can see how much rubbish they mindlessly dump on the ground.

That they can spit at the table, (men) take off their shirts at the table if it is warm, pick and blow their noses, and use a toothpick while still seated yet react in horror when they see one of us pick up a morsel of food with our fingers...

Should also mention the waiting sometimes they can be pushy from elevators to subway doors wanting to be the first out.
But when they hit a fast food place or ATM they take an age to order or get money out. Even though they have been waiting in line for 3min they still dont know what they want to order.
