Why not sell oil incense in the market?

The procedure is very complicated. Oil fragrance is a special snack of Hui people, and it can be seen everywhere in the streets and alleys of Wuhan in the 1970s. It is similar to the oil incense sold in the market. The most important thing is that there are not many strict procedures. The production procedures of Huimin oil incense are complicated, which makes it rare in the market. The oil fragrance on the market is only fried food that satisfies the taste buds of diners.
