The dynasty founded by the "First Emperor" divided the whole Empire as it then was into thirty-six _chün_ or provinces, and Wên-têng formed part of the Ch'i province. At last, in the sixth year of Kao Tsu of the Han dynasty (201 B.C.), a Chinese magisterial district was founded in the eastern peninsula for the first time, though the city chosen as the centre of government was not Wên-têng but a place called Pu-yeh-ch'êng, and the _hsien_ or magisterial district was accordingly known as Pu-yeh-Hsien. This city, which is said[28] to have been founded by one Lai-tzŭ in the "Spring and Autumn" period twenty-five centuries ago, is now a small village in the modern Jung-ch'êng district, a short distance from the British frontier on the Chinese side, and whatever glory it may once have possessed has totally departed. The origin of the name, which means "Nightless," is unknown, though naturally one would like to connect it in some way with the Sunlit Vale of the astronomer Ho. The new _hsien_ city was assigned to the prefecture of Tung-lai, then the most easterly prefecture in the province. From this time onward all the north-eastern part of Shantung, including the districts with which we are specially concerned, remained under the civil administration of China. From time to time various changes were made in the seat of district-government and in the boundaries of the prefectures, but these it would be superfluous to follow in detail. In the fourth year of T'ien T'ung (568 of our era), Wên-têng city became the magistrate's headquarters, and the district was placed in the Ch'ang-kuang prefecture under the name of Wên-têng-shan Hsien. Early in the period K'ai Huang (581-600), the abolished Ch'ang-kuang prefecture gave place to Mou Chou, and Wên-têng was placed in the Tung-lai prefecture, to which Pu-yeh had formerly been assigned. Passing over many similar administrative changes of no special significance we come to the Ming dynasty, which began to reign in 1368. In the ninth year of Hung Wu (1376) the present prefecture of Têng-chou was created. Both Wên-têng and Ning-hai districts were assigned to the new prefecture and have remained under its jurisdiction ever since.
