In addition, more and more people are traveling to the Northeast and experiencing the unique charm of Northeastern cuisine, which has attracted wider attention and promotion.

2. Northeastern cuisine is a home cooking and processing methods. Northeastern people's tastes are more on the greasy, heavy, Northeastern cuisine uses a wealth of seasonings, but they are all household seasonings, such as green onions, ginger, garlic, as well as soy sauce, bean paste, etc., the cost is not high.

3. Staff wages are relatively low. Most of the cities in the northeast of the economy is relatively backward, the income level is relatively low, so the staff's wages are correspondingly low, which also led to the price of the northeast food is more affordable.
