Ma Huang, the owner of Delamu, has been in Binzhongluo for 8 years and has trekked and driven all over the place. He has scores of local stories and is a font of local info. If for nothing else, he is worth the visit.
The teahouse is full of local bits and pieces, and is a comfy place to drink one of his carefully selected teas of an afternoon. See if you can get invited for dinner - he likes to put house guests together - as his wife is a great cook and his truffle infused liquor is delicious.
