As for you, the success rate is very small. First, unless you are willing to pay a lot of money to teach you, no Uighur master will accept you as an apprentice. Second, even if it is successful, opening a store in Xinjiang will soon close down, even if it is in Hunan, it may not be successful. Because you can never make the delicious taste made by Xinjiang people. This can be explained by the huge difference between the mixed noodles made by the Hui people in Xinjiang and the mixed noodles made by the Uighurs. Third, there must be someone in Hunan who sells Xinjiang naan. If there are Xinjiang people selling naan, you will face bankruptcy.
Nan, a specialty of Xinjiang, has been cooked and eaten by Xinjiang people for a day or two. You can't learn that skill in a short time. If you want to make authentic naan, you need time to practice. I'm afraid you don't have that much time to spend on it.
