Friend, what special snacks can't be missed when traveling to Changsha?

I have been to Changsha several times, and the black classic stinky tofu and Xiangqun fried dumpling in Pozi Street are all must-eat. There is also Wang Han's Peirong Bookstore in Changsha, which is located on the 24th floor of Bobo International, Jiefang West Road. The environment is good and quiet. The old man who looks at the bookstore is very nice, but the air conditioning is not good in summer, and reading in it is particularly hot. Pay attention to taxis in Changsha. When standing in the street and waving, many black people will stop.
