Why is there no single city in Lu 'an?

Low demand. The same city is a courier received in different parts of the same city. Because there is no flash demand in the same city, it shows that the flash demand in this area is very low, and the flash volume in every place is not very high. In first-tier cities, there is indeed a large amount of flash in the city center. The demand in Lu 'an is relatively low, so there is no single city.
