The word "nine" in the nine-turn large intestine is very meaningful. In China culture, "nine" is the largest number, representing supremacy, and it is also widely used in the field of food culture because of its homophonic auspicious meaning. The "nine turns to large intestine" in Shandong cuisine is a typical example.

Jiuzhuan large intestine was first created in Guangxu period. At that time, there was a Jiuhua Building in Jinan City, and the boss's surname was Du. It has nine stores in Jinan, and the hotel is one of them. The shopkeeper is particularly interested in the word "nine". Everything should be counted as nine, so the names of his shops are all prefixed with the word "nine".

In modern times, chefs have improved the "nine-turn large intestine". First, the length of fat sausage is standardized: each part is cut into about 60-70 cm. Secondly, the processing technology of ingredients is complicated: the intestinal layer of "chain cover" should be covered with eight or nine layers, which greatly exceeds the previous two or three layers. Thirdly, add more seasonings in the cooking process, such as cooking wine, cinnamon noodles, white pepper, soy sauce, vinegar, chopped green onion, pepper oil, chopped coriander and so on. The "nine-turn large intestine" made in this way has a rosy appearance and is placed on a plate, just like the red sun rising in the East China Sea, which is radiant and can arouse people's appetite at a glance. At the entrance, the outer layer of the intestine is crisp, the inner layer is delicate and tender, and the salty, sweet and sour gravy gushes out, and the oil suddenly overflows the mouth. The taste buds can be conquered in an instant with a slightly tough, fragrant, soft and glutinous taste. Especially the intestines are mixed with rich soup, and the taste is even more enjoyable and intoxicating.
