How long the Chinese colonists who settled in Shin-han preserved their language and customs is not known. Though these were lost after a few generations, yet it is evident that their influence on the aborigines of the country was very great. From first to last Shinra excelled in civilization all the petty states in the peninsula, of which at first there were seventy-eight. Unlike the Ma-han, the Shin-han people lived in palisaded cities, and in houses the doors of which were on the ground and not on the roof. They cultivated mulberry-trees, reared the silk-worm, and wove silk into fine fabrics. They used wagons with yoked oxen, and horses for draught, and practised “the law of the road.” Marriage was conducted with appropriate ceremony. Dancing, drinking, and singing were favorite amusements, and the lute was played in addition to drums. They understood the art of smelting and working iron, and used this metal as money. They carried on trade with the other han, and with Japan. How far these arts owed their encouragement or origin to traders, or travelling merchants from China, is not known. Evidently Shinra enjoyed leadership in the peninsula, largely from her culture, wealth, and knowledge of iron. The curious custom, so well known among American savages, of flattening the heads of newly born infants, is noted among the Shin-han people. Neither Chinese history nor Japanese tradition, though they give us some account of a few hundred families of emigrants from China who settled in the already inhabited Corean peninsula, throws any light on the aborigines as to whence or when they came. The curtain is lifted only to show us that a few people are already there, with language and customs different from those of China. The descendants of the comparatively few Chinese settlers were no doubt soon lost, with their language and ancestral customs, among the mass of natives. These aboriginal tribes were destined to give way to a new people from the far north, as we shall learn in our further narrative. The Japanese historians seem to distinguish between the San Han, the three countries or confederacies of loosely organized tribes, and the San Goku, or Three Kingdoms. The Coreans, however, speak only of the Sam-han, meaning thereby the three political divisions of the peninsula, and using the word as referring rather to the epoch. The common “cash,” or fractional coin current in the country, bears the characters meaning “circulating medium of the Three Kingdoms,” or Sam-han. These were Korai in the north, Shinra in the southeast, and Hiaksai in the southwest. Other Japanese names for these were respectively Komé, Shiriaki, and Kudara, the Chinese terms being Kaoli, Sinlo, and Pe-tsi.
