The Yanshi Jiashun (Family Instructions of Mr. Yan) mentions a Zhu Zhan who lived in Jiangling. A good scholar with no money, he didn't eat for many days, until it got to the point where he was eating paper. He wouldn't slaughter his dog to relieve his own hunger, and because it was winter and he lacked blankets, he and the dog cuddled together for warmth when they slept.
「顏氏家訓」裡提到世居江陵的朱詹，好學家貧無資，累日不炊，到了吞紙裹腹地步，他也並未將狗給宰了填饑，而是寒無氈被，抱犬而臥，互相取暖。
