《太平广记·卷四百一十五·草木十》
到了天亮，卢虔让人查寻鬼的踪迹，来到宅子东面的一块空地上，见一棵一百多尺高的柳树上，扎着一支箭。这就是所谓的柳将军。
至明，虔命穷其迹。至宅东隙地，见柳高百余尺，有一矢贯其上，所谓柳将军也。
When it was dawn, Lu Qian asked people to search for the ghost's traces. They arrived at an open space on the east side of the mansion and saw an arrow embedded in a willow tree that was over a hundred feet tall. This was the so-called General Willow.
