《徐霞客游记·粤西游日记七》
找到一个黄金洞就既能得知当地人所不知道的东西，又能知道当地人误指之处，而且又知道它是古代名贤遗留下来的；只是没有听说过苏东坡到过桂林，这一点值得怀疑。
一黄金洞而既能得土人之所不知，又能知土人之所误指，且又知其为名贤所遗；第东坡不闻至桂为可疑耳。
Finding a Golden Cave can not only tell me what the locals do not know, but also where they are mistaken, and that it is left by ancient celebrities; but I have never heard of Su Dongpo visiting Guilin, which is worth doubting.
