《徐霞客游记·楚游日记十一》
到了半边山，下到牛头河边，夜色已经合拢，幸好已经过了危险处。我叫导游领我们从小路直奔韭菜原，因为这地方有高山瑶居住，而从这里往南，绝无一间小屋，要直抵高梁原才有瑶族人家居住。
至半边山，下至牛头河，暝色已合，幸已过险，命导者从间道趋韭菜原。盖以此处有高山瑶居上。自此而南，绝无一寮á小屋，直抵高梁原而后有瑶居也。
When we arrived at the foot of the halfway up the mountain, it was already nightfall, but fortunately we had already passed through the dangerous places. I asked the tour guide to lead us on a shortcut straight to the Leek Field, because the Yao live in the highlands there, and going south from there, there is not a hut, until you reach Ga梁Yuan to find Yao people living.
