Have you ever seen the real Bathroom in China and Korea outside big Cities ? OMG, Once you see it, you don't want to eat anything.
In small cities outside Kung Seoul, They pretty much the same as in Laos. just walk in there and Dumb it down clean up and leave. Sometime the worms just walk up all over the Toilet seat. Please don't assuming Korea is modern in everything, Nahhh.
In China, in country side, this is from tourist from the west i knew told me, you line up take your turn. and each tourists has their own small bucket because you gonna shiet it in that bucket and leave it there for the people right behind you take it out, But, you have to take the bucket of the guy a head of you out...
Sound weird ! But, true...
As for the toilet you show it in here, I'll take that anytime Man, and it look like a little modern with flashing arm right behind 555. But, i know i will have a problem with sit down all the way, it probably gonna hurt my tendon a little bit because we got use to sit on a toilet Bowl, 555.
