I was daunted at the prospect of using the Chinese toilet, but time taught me that squat toilets are more hygienic and far easier to clean than ours. The thing is, a person needs to be able to squat.
Back then (maybe still?) a person needed to carry his/her own toilet paper, 卫生纸, pronounce “wei shung zhi”, the first two characters being the word for “toilet.” I lived in China 10 months without knowing how to say those characters, only how to read them.
This style of toilet is pretty common throughout the world — I encountered them at the Miramare Castle in Trieste, Italy.
