That spicy vegetarian dish is also delicious. It's all vacuum-packed, and you can't buy it outside the province, such as Renzai and BBK.
As for shrimp, snakes, stinky tofu, etc. Although they are all delicious snacks, they are not easy to package. Come to Changsha when you have the chance.
Sauced duck is also a special snack, but now it is vacuum-packed. I wonder if it was bought outside the province.
I hope it helps you.
