One of the first things I noticed on campus was the presence of large, colored thermoses everywhere. The students fill them up every day with fresh, hot water from the hot water station right next to the coal-burning building that heats the hot water and then take them back to their dorms. The students have to pay for their hot water for their thermoses (used for drinking and keeping warm) as well as the hot water used to take showers.
The students drop their thermoses off near the water-filling station before they go to lunch or dinner so there are always huge groups of thermoses around. I don't know how the students tell them apart because so many of them look the same and I believe Ken has asked them before why they don't switch them around on each other as a practical joke, but they aren't really into that kind of tomfoolery.
When tutors come over to my house they are always impressed that I have drinkable hot water available right where I live and for free! Yep, it's a regular life of luxury here in Changzhou, but I might buy a giant colored thermos just to fit in.
The most terrible thing is that we often lost our thermoses without any reason. Most were stolen for unknown reason. But fortunately I didn't lose any thermose during my college life~~~
