《宋书·志·卷三十四》
草木的变异，还把它看作祥瑞，现在二人同一颗心，《易》中称 二人同心，共同的力量可以断金，吉祥的征兆现在显现，又出现在陕东之国，这正是四海同心的祥瑞，我禁不住内心的喜悦，谨画好图呈献。 
草木之异，犹以为瑞，今二人同心，《易》称 二人同心，其利断金 。嘉征显见，生于陕东之国，斯盖四海同心之瑞，不胜喜踊，谨画图以上。 
The mutation of grass and trees is still regarded as auspicious. Now the two have the same heart. According to the "Book of Changes," "two people with the same heart can break gold with their combined strength." Auspicious signs are now evident and they have appeared in the country of Shandong. This is exactly the auspicious sign of the same heart all over the world. I can't help but feel happy in my heart. I carefully draw the picture and present it.
