“夜郎自大”的典故出自2000年前的夜郎古国,但因历史久远,今天人们已难见这西南古国的遗迹。夜郎古国存在了300多年,其文明在西南地区有较大影响,延续至今的“竹崇拜”“牛图腾”与斗牛、斗狗等独特民族风情构成了内涵丰富、扑朔迷离的夜郎文化。1996年,旅美艺术家宋培伦移居贵阳深山,精心构造,雇匠砌石,用20年光阴打造了一片奇幻城堡——花溪夜郎谷。 “Yelangzaga ” allusions from the Yelang ancient countries before 2000, but because of the long history, today people have been hard to see the remains of this ancient southwest. The ancient state of Yelang existed for more than 300 years and its civilization had a great influence in southwest China. The unique national customs such as “Bamboo Worship ” and “Bull Totem” and the bullfighting, fighting dog and so on constitute the connotation of rich and confusing night Lang culture. In 1996, Song Peilun, a traveling artist from the United States, moved to the mountains of Guiyang and carefully constructed and hired masons to create a fantastic castle - Yelang Valley in Huaxi with 20 years of experience.
