before it reached the coast line the Tang clan acquired considerable influence all over the semi-independent regions of South-east Kwangtung. They became feudal overlords of the populations and, as long as they could, helped to govern the territories they controlled for the Sung Emperors. When the Sungs were finally overcome and the Tartars reached the coast, their rôle became more that of farmers concerned in opening new areas to cultivation. They were pressed more closely into our region, and their political influence declined, although their cultural influence, absorbing as it did all the aboriginal elements and changing them into the Chinese mould, was potent and lasting.
The only source of the accounts of the Tang migration is in the family genealogy which was compiled in the Ming dynasty. It is based on authentic family records and although it contradicts itself in certain particulars, especially in dates, it must be regarded as an exact account. According to this genealogy the first ancestor of the local branch was Tang Han Fei who held an official post under the Sung dynasty in Kiangsi province. A preface to the genealogy says that he visited Kwangtung province but admits that it is not clear whether he reached this region or not. His great grandson Tang Fu Hsieh is considered the founder of the local branch. This man was a scholar who passed the public examination either in A.D. 1069 or 985 according to different versions. He, too, held an official post in Kiangsi and on retirement settled at Kam T'in, a fertile area north of the T'un Mun Valley. He brought from Kiangsi the bones of his forefathers which were buried in selected sites. The graves still exist and are particularly venerated by the Tangs.
It was Tang Fu Hsieh who carved the inscription which commemorates Han Yü on the summit of Mount Tun Mun and he also founded a school and a library at Kam T'in. His sons and his grandsons, however, did not stay there. They migrated further north into Tung Kun district where they founded houses which exist to this day. Owing to the presence of the family tombs, Kam T'in remained the property of the family and was probably visited every year, although they did not actually reside there. Three generations after Tang Fu Hsieh, five of his descendants, known as the "five Yuans" from their first names, made a division of the whole family properties which by then extended all over
