Tianjin, one of the four municipalities directly under the Central Government in China, is located in the northeast of the North China Plain and is the closest seaport to Beijing. The city is one of the biggest industrial and port cities in China and it is also known as "the diamond of the Bohai Gulf".
Tianjin has a long and illustrious history, from an ordinary fishing village to the most important trade center in Northern China. Tianjin was considered to be one of China's most important military fortresses in the Yuan Dynasty (1271-1368) due to its particular geographic location as access point to Beijing, the national capital. Its name "Tianjin" was graciously bestowed by the Emperor Zhudi in the early years of the Ming Dynasty (1368 - 1644). Tianjin means "the place where the emperor crossed the river". In 1860, after the First Opium War, Tianjin was further expanded to become the second largest business and communications center in the country. By the end of the 19th century, it had grown into a bustling center for international commerce.
