Some of these are personal and more likely to be referred to as “I know I live in China when….”
You’ve seen a child use the facilities whilst outdoors in a public area, not in a secluded area with brush or forest cover.
Normal conversation includes your marital status, salary, nationality or other questions deemed private by American standards.
Haggling, and whittling down the price, even by a few mao excites you, maybe even serves as the highlight of your day.
People stare, point at you or you don’t blend into crowds.
You drink hot water, avoid fruit and cold food or beverages during “that time of the month,” eat raw garlic without giving it a second thought (ok, I guess that’s more personal as Suigetsu commented on said topic).
You don’t even give a porcelain squatting toilet or even a mere channel a second glance. 没办法 because nature calls. You make sure to arm yourself with toilet paper or tissue at the off chance you need to use the facilities.
人山人海, especially during public holidays and at tourist attractions, there are seas of people.

You can buy 黑人牙膏 or “Black Man Toothpaste,”a brand that features a picture of a black man with pearly whites.

You also stare at other foreigners.
Seeing groups of men squatting, sleeping, or just hanging out on the street is completely normal.
People walking around at all times of the day is normal.
Going out to eat is cheap and delicious, not an expensive outing
One person pays the bill
You can get good produce and food at small stores, and there are at least five stores in a nearby walking radius that sell the same stuff as supermarkets.
One street might have three of the same store type.
You don’t need a car because stuff is nearby, or public transportation is good.
Adults go out and have fun (KTV, walking around, etc.)
Drinking baijiu or alcohol at lunchtime is fine, and drinking in public is also fine (It’s 5 p.m. somewhere, right?)
