In China, the meaning of "special dishes" is different in different periods. In the 1980s, "special dishes" mainly referred to vegetable varieties introduced from abroad, such as broccoli, lettuce, purple cabbage and celery. From the late 1980s to the early 1990s, a new round of vegetables imported from abroad appeared in China, such as cherry tomatoes, kale, Brussels sprouts, fennel bulbs, sweet apricots and softened chicory. However, the "special dishes" introduced in the 1980s have been familiar to the vast number of producers and consumers, and have gradually withdrawn from the ranks of "special dishes". In addition, some local varieties of rare vegetables, wild vegetables, novel sprouts and other high-quality high-grade vegetables have quietly appeared in China's vegetable market, greatly expanding the scope of "special dishes." Therefore, the general term of "specialty dishes" is used to refer to local relatively novel vegetables. In different periods, the scope of "special cuisine" has different connotations. "Special cuisine" is a dynamic concept, which is constantly changing with time and place.
