1. Lhasa: Due to its remote location, inconvenient transportation, and the influence of ethnic habits, Lhasa's dining culture is relatively homogeneous and lacks diversity.
2. Korla, Xinjiang: Although Xinjiang is known as the "Kingdom of Kebabs", the city of Korla is relatively desolate, the development of the catering industry is lagging behind, and the variety of food is relatively small.
3. Yichun, Heilongjiang: Located in the north of China, Yichun has a cold climate and fewer varieties of agricultural products, so the restaurant industry is relatively slow to develop and the choice of food is limited.
4. Alxa League, Inner Mongolia: Also located in the north of China, Inner Mongolia has a dry and barren climate, and most of the local residents are grassland herders, which makes it lacking in diversity and specialties in terms of cuisine.
In short, you need to know about the cuisine in advance when traveling in these cities and take care to carry enough dry food and rations.
