According to the Records of Things Heard and Seen (Wenjian Lu), it is a common saying that lending a book is one chi, and returning a book is one chi. I once doubted this, as lending and returning books are standard practices, so why would they be called foolish? Later, I saw a letter from Wang Le-dao to Qian Si, which stated: The Ode to the Expedition (Chushi Song) is most exquisite; the old saying is to borrow a book for one chi, and return a book for one chi. Only then did I realize that people today have mistakenly corrupted the character chi into the character for foolish. Additionally, according to the Rhyme Dictionary (Yunhui), it can also be used interchangeably with the character for owl. According to a poem by Huang Ting-jian: At times I send one owl to smooth my furrowed brows. Additionally, according to the Collection of Rhymes (Jiyun), pronounced chi. The meaning is the same.
