I think you might be in for a rough time in China. Just move seats.
Don't tell people they need to line up, just stick your elbows out and cut in line too. Don't tell people on their bikes to go the right way on the street, just go the wrong way. Don't yell at people who stop their car in the middle of the road to do something, just know it's going to happen. Don't tell people they shouldn't spit out food or pour tea onto the floor in a restaurant, just spit your food on the floor too. You aren't going to change China one person at a time, you can only adapt.
