After introduced about Anhui, Cantonese, Fujian, and Hunan cuisines, I will introduce the other four famous cuisines in Chinese traditional cook. They are Jiangsu, Shangdong, Szechuan, and Zhejiang cuisines.
1. Jiangsu cuisine
Jiangsu cuisine is characterized as soft texture, but not  to the point of mushy or falling apart. For example, the meat tastes  quite soft but would not separate from the bone when picked up. Other  characters includes the strict selection of ingredients according to the  seasons, emphasis on the matching colour and shape of each dish and  emphasis on using soup to improve the flavour. One example is the steamed meatball. 
2. Shangdong (Lu) cuisine
Shangdong cuisine is well-known to use local seafood ingredients, such as scallops, prawns, clams, sea cucumbers, and squid. It is somewhat unique for its wide use of corn, peanut crops,  wide variety of small grains such as millet, wheat, oat and barley.Also Shandong cuisine's greatest contribution to Chinese cuisine has been in the area  of brewing vinegars. Left picture is sugar and vinegar fish, a very popular dish in restaurants. 
3. Szechuan (Chuan) cuisine
Szechuan cuisine is well-known for using garlic  and chili peppers, as well as the unique flavor of the Sichuan peppercorn. Peanuts, sesame paste and ginger are also prominent  ingredients in Szechuan cooking. The Sichuan peppercorn is is an indigenous plant producing peppercorns which  has an intensively fragrant, citrus-like flavor and produces a  "tingly-numbing" 
sensation in the mouth. Common preparation techniques in Szechuan cuisine include stir  frying, steaming and braising. One famous dish is double cooked pork, shown in the right picture here.
