i was going to post the Lixiang & Biyun Go Crazy (as usual) photos but Lixiang beat me to it (refer to his blog). then again we can never have too much of a good thing, so here goes ;p

for the uninitiated, photos 2-4 are supposed to represent 喜怒哀乐, 2 encompassing both 喜 and 乐. as for the theme of the first...your guess is as good as mine haha.
