Jiangsu is bordered by the Yellow Sea to the east, the Huai River to the north, the Yangtze River to the south, and the Beijing-Hangzhou Grand Canal in the middle. It has many rivers and lakes, is the province with the lowest average elevation in China, and ranks first in the country in terms of the proportion of both plains and water surface. The journey into Jiangsu begins on an island in the Yellow Sea, encountering the beautiful danling cranes in the largest wetland by the Yellow Sea, and then flying south along the coastline to reach the mouth of the Yangtze River, tracing the past life of a port.
