It took a long time for the city to come into being. In ancient times, sea water receded from what is Tianjin now. For three times, the Yellow River, with the highest content of sand in theworld, flowed through this place into the sea, thus forming Tianjin Plain. Even today, a few seashell dikes of ancient times can still be found in such places as Shanggulin in Tianjin.According to research findings, these dikes are the remains of the ancient coastal lines.
The name of "Tianjin", meaning "a port for the emperor", was first adopted in the first year of Yongle Reign in Ming Dynasty. In the second year of Yongle Reign (1404), Tianjin became a walled garrison. In 1860 Tianjin was opened as a trading port. In the1930s, Tianjin became the largest industrial and commercial city and financial center in the north of China.
After the founding of the People's Republic of China, Tianjinbecame a municipality directly under the central government. In1978, with the adoption of the policy to reform and open up tothe outside world, Tianjin became one of the first coastal cities inChina to open up.
