On January 2, 2017, Mr. Zhang took me to Changsha, where I can eat stinky tofu. There are many types of stinky tofu here. There is a black classic, that is, there is a hole in the middle. I put the side dishes in it and then eat them. I summed up three kinds. Black classics are one of them. Another is Huangxing Road, the Changsha stinky tofu, there is no hole in the middle, the tofu is fried there, sprinkle small ingredients, there is soup, Mr. Zhang favorite, and another is Wenheyou stinky tofu, my favorite.
