One time I was having breakfast in the dining car, watching the scenery of somewhere in the Northern mountains, when some railway personnel came in for a break. They were all young, robust, and earthy, with strong Northeastern accents. After a few smokes they noticed me, a waiguo, and called over, asking if I'd like to hear them sing some Northeastern folk songs. They sang beautifully and heartily, telling me a little about each song, then had to return to work.

Absolutely sublime. ^ ^ ^
