Buddhists are all vegetarians.
And there are lots of buddhists living in Chengdu.
As a vegan, you gonna enjoy living in this city.
If you ever wanna eat out, Wen Shu Yuan (文殊院) is your best choice.
Most restaurant servers there think they are sinners. Therefore, they volunteer to work there to redeem themselves.
Food there are delicious. All made of beans or vegetables. But taste is really good. I hope you enjoy their food.
