HONG KONG BEFORE THE BRITISH
151
Tonkin delta set up an independent kingdom comprising both the Tonkin and Canton estuaries. His capital was Pun Yü, the modern Canton, and was the first walled city to be built in Nan Hai. The connection between North China was kept up and tribute was sent regularly to the Northern capital.
By this means the routes between Kwangtung and the Yangtze were developed. An important step was the opening of a canal which made a complete water route between the Yangtze via the Tung Ting Lake to the west river at the modern Wu Chow and thence to Canton. The canal exists to this day. When the kingdom of Nan Hai was finally subdued by the Hans in 111 B.C. a Chinese river fleet descended by this route onto Pun Yü and sacked it. After this victory the Han emperors extended their direct rule over the whole of the coast line from Canton to the Tonkin delta and farther south to places in modern Annam.
Min Yüeh, that is the eastern part of Kwangtung, the whole of Fukien and a part of Chekiang, continued to be governed more or less independently. There was no extensive colonization by the Hans probably because their effort was directed towards the west and their ambition to link up through India their vast empire in the North West with the conquests they had made in the South. Not being a maritime people and possessing only a river fleet they were not interested in maritime routes, and the only effort they made on the sea was the conquest of Hainan Island.
For this reason the earliest settlement of the Chinese spread west, not east, from Pun Yü, across Kwangtung and Kwangsi provinces. We can trace it in the walled cities built at that time. There were a group of them round the present site of Canton which have now been abandoned. Wu Chow or Ts'ang Wu was the point of contact on the west river, between it and Chiao Chih or Hanoi was the modern Nanning or Wu Lin. There were other towns built on the littoral such as Lim Chow and Ko Chow.
The Chinese inhabiting these cities were soldiers, political exiles and traders. There cannot have been much agricultural settlement. In the fortified centres the Han conquerors taught the natives some of their arts, the use of metals, as we have seen, was among them, and in exchange took all the produce and sent it to North China.
