Today i have China Day! All cards i got today (10!) are from China.
This one was sending by king and shows the old town called Chongqin in the big city Zongshan Town which has over 1 Mio Inhabitants. For me this is unbelievable! 1 Mio peops in one town. more than 700 inh. per km2 - ooo my god! Bern, where i'm living, has 2,5 :) And i just checked: No city in Switzerland has more than 12 inh. per km2!
