There really aren’t many blogs about Chengdu, but here are a couple:
Chengdu Music – interviews with bands, DJs, and stuff about local shows in the city
Eat Drink Chengdu – Great blog about Chengdu’s food culture, not updated in a long time but still lots of relevant info
China Urban Development – not specifically about Chengdu, but authored by an American who lived in Chengdu for a few years, so Chengdu comes up frequently. We interviewed him here
Chengdu’s and Don’t – A personal blog about living in Chengdu, a good account of what life in the Du is like
There’s also our links page with a lot of other sites, most of them aren’t specifically about Chengdu but relate to greater China.
