鲁迅在小说《孔乙己》中,有一段关于孔乙己教小伙计写字的细节描写: “……孔乙己显出极高兴的样子,将两个指头的长指甲敲着柜台,点头说,‘对呀对呀!……回字有四种写法,你知道么?’我愈不耐烦了,努着嘴走远。孔乙己刚用指甲蘸了酒,想在柜上写字,见我毫不热心,便又叹一口气,显出极惋惜的样子。” In the novel “Kong Yiji,” Lu Xun had a detailed description of Kong Yifa teaching the young man how to write: “... Kong Yiji showed a very happy appearance. He knocked the long fingernails of two fingers on the counter and nodded and said, ’Yes, Yeah right!! There are four ways to write back words, do you know? ’I’m getting more impatient, and I’m pouting to go far. Kong Yiji just used her nails to pick up the wine and wanted to write on the counter. I didn’t show enthusiasm. Then he sighed again and showed a great pity.”
