I don't know. Zhangjiajie and Changsha Phoenix can do it. For Changsha, I recommend several places. One is that the whole street in Nankou is full of snacks. Buy whatever you see good. Not expensive. The more famous ones, such as the four-faced Buddha, stinky tofu and spicy pot, are good (hot pot but fried). Delicious shrimp tastes like sugar and oil, but the sanitary conditions in the south gate are relatively general. You can also go to the alley at the gate of Simen. There are many very good snack bars with good sanitary conditions, as well as many dessert shops and Princess Rorty's bakery, all of which are delicious. There is also a fruit rhapsody near Zhongshan Pavilion. The names of various dessert smoothies are strange but super distinctive! I've been to Phoenix three times ... Personally, I think it's good to choose a restaurant in a busy neighborhood. My favorite food is blood duck. I go out to the store to eat powder in the morning! Phoenix rice noodles are really delicious ~ the powder is good because the water is good. Phoenix also has ginger candy. In fact, Phoenix doesn't care what special snacks are basically commercialized. Buy whatever you catch.
