Jiangsu (江苏; Jiāngsū)  is one of the most attractive tourism destinations in Asia and located on a 500-mile (900 km) stretch of the Yellow Sea on China’s east coast. You can “taste” all of the best that China has to offer in the province, from Ming Dynasty walls and tombs to the delicate and fresh Huaiyang cuisine. The wealthiest province in China, Jiangsu is home to the mighty Yangtze River; China’s ancient engineering Wonder of the World in the Grand Canal; the World Heritage Listed Chinese classical gardens of Suzhou; the famous Confucius Temple and Mausoleum of Sun Yat-sen in Nanjing; and it’s the best place to see the unique living water villages of the Yangtze River delta. The many hidden treasures of Jiangsu include the Terracotta warriors of Xuzhou; the former residence of Nobel prize-winning American author, Pearl Buck; and endangered species of birds and animals.
Jiangsu has 14 prefectures, around the following 14 cities:
Jiangsu is well connected by road, rail and air to the rest of the country and world.
Shanghai has many international flights and Nanjing some, including a new direct service to Frankfurt on Lufthansa; both those cities also have many domestic flights. Wuxi, Nantong and Changzhou have airports for domestic flights.
There are good bus and train links within the province, plus some boats on the Yangtze and other waterways.
The roads are good so you could consider renting a car and driver, or even driving yourself. See Driving in China.
Jiangsu can be broadly divided into two linguistic regions. The southern part of the province is Wu speaking while the northern part is Mandarin speaking. The Suzhou (not Shanghai) dialect of Wu is traditionally considered to be the prestige dialect, so learners Wu will find it spoken in the "purest" form there. The Nanjing dialect of Mandarin differs significanly in pronunciation from standard Mandarin, but nevertheless is still mutually intelligible.
The Presidential Palace. Historically the site of a number of important government officials, it is also a beautiful garden, an oasis from the noisy, bustling city. About ¥40 a person.
Purple Mountain. Although the base is crowded, for ¥60 a person, there is a chair lift to the top which is scenic. Again, a nice getaway from the city.
Suzhou has many water-towns. These are cities interlaced by rivers and streams. The main means of tranportation was once by water. Zhouzhuang is the most famous of the water townships.
