《管子·轻重丁》
商人带着货物，销售则急于脱手，收购则急于买进，买卖未完而提早结束，离开货摊，捕捉蚊母之类的大鸟去了。刚成年的青年，也都争先恐后地挟弹怀丸往来于水上，弹打翡翠、燕子一类小鸟，直到夜暮方休。
贾人蓄物而卖为雠，买为取，市未央毕，而委舍其守列，投蚊虵巨雄；新冠五尺请挟弹怀丸游水上，弹翡燕小鸟，被于暮。
Merchants carry goods and are eager to sell them, and are eager to buy them. Before the transaction is over, they leave the stall early and catch big birds such as mosquito mothers. Young men who have just turned adults also rush to carry bullets and carry rounds of water, playing with emeralds and swallows until dusk.
