The kingdom of Ruirui芮芮國
1The kingdom of Ruirui
芮芮國，蓋匈奴別種。魏、晉世，匈奴分爲數百千部，各有名號，芮芮其一部也。自元魏南遷，因擅其故地。無城郭，隨水草畜牧，以穹廬爲居。辮髮，衣錦，小袖袍，小口袴，深雍靴。其地苦寒，七月流澌亘河。宋升明中，遣王洪軌使焉，引之共伐魏。齊建元元年，洪軌始至其國，國王率三十萬騎，出燕然山東南三千餘里，魏人閉關不敢戰。後稍侵弱。永明中，爲丁零所破，更爲小國而南移其居。天監中，始破丁零，復其舊土。始築城郭，名曰木末城。十四年，遣使獻烏貂裘。普通元年，又遣使獻方物。是後數歲一至焉。大同七年，又獻馬一匹、金一斤。
The kingdom of Ruirui, that is, the Rouran, is a separate branch of the Xiongnu. In the age of Wei and Jin the Xiongnu were divided into hundreds and thousands of tribes, and each had its own name, and Ruirui was one of those tribes. After the Yuan Wei moved south, Ruirui took their old land for itself. They have no walled towns. They follow the water and the grass and pasture their herds, and they make their homes of round felt tents. They braid their hair and wear brocade, robes with small sleeves, trousers narrow at the ankle, and boots deep in the top. Their land is bitterly cold, and even in the seventh month drifting ice stretches across the rivers. In the Shengming years of Song, Wang Honggui was sent there as envoy to draw them in and strike Wei together. In the first year of Jianyuan of Qi, when Honggui first came to that kingdom, the king of the kingdom led three hundred thousand horsemen and went out more than three thousand li southeast of Mount Yanran, and the men of Wei shut their passes and did not dare to fight. Afterward Ruirui grew weak little by little. In the Yongming years it was broken by the Dingling, became a small kingdom again, and moved its dwellings to the south. In the Tianjian years it broke the Dingling at last and won back its old land. It built walled towns for the first time, and the name of the town was Mumo. In the fourteenth year it sent an envoy to offer a robe of black sable, and in the first year of Putong it sent an envoy again to offer the products of its country, and after this it came once in several years. In the seventh year of Datong it offered one horse and one catty of gold as well.
2The art of calling up wind and snow
其國能以術祭天而致風雪，前對皎日，後則泥潦橫流，故其戰敗莫能追及。或於中夏爲之，則曀而不雨，問其故，以㬉云。
That kingdom can sacrifice to heaven by an art of theirs and bring on wind and snow, so that before them is a clear sun while behind them muddy water runs across the ground, and for this reason no one can overtake them even when they lose a battle. When the art is worked in China (中夏), it only grows overcast and no rain comes, and when they are asked the reason they say it is because the land is warm.
