The G1504 Ningbo Ring Expressway The G1523 Ningbo–Dongguan Expressway Rapid rail transit and subway Ningbo has multiple metro lines in service, under construction, and under authorized planning: Since the Metro lines above mainly serve the 6 urban districts of Ningbo, the Ningbo government announced several future plans to built further rapid transit to connect the 6 urban districts with the county-level cities and counties. Military Ningbo serves as the headquarters of the East Sea Fleet of the Chinese People's Liberation Army Navy. Culture As a city with giant ports, Ningbo influenced many countries near China, such as Japan. Language Ningbo speech is a dialect of Wu Chinese that has preserved many aspects of ancient Chinese phonology. Its original wording mode can be found in classical reference books. After the unequal treaty port opening, western culture gradually permeated Ningbo. Thus, the prefix " yang", meaning ocean or Western, before the nouns of imported goods is a special language phenomenon of Ningbo dialect. Food Ningbo is known for Ningbo Tangyuan, small stuffed buns which are boiled. The stuffing is usually ground sesame mixed with sugar or pork fat. The stuffing is then wrapped with sticky rice powder. Ningbo is even more well known throughout China for its seafood. Seafood markets are abundant, carrying extensive varieties of fish, shellfish, snails, jellyfish and other invertebrates, and sea vegetables in all stages of preparation from "still swimming," to cleaned and ready to cook, to fully cooked. Festivals While the Mid-Autumn Festival is usually celebrated on August 15th of the Lunar Calendar, Ningbo celebrates the festival a day later on the 16th. The most creditable history for this is that long ago, the whole city waited for Shih Hao, a Southern Sung prime minister, to celebrate the festival.
