《韩非子·外储说左上》
我范睢张弓时就不是这样：用校正工具校上一天，随即装上弦，上弦三十天后才把箭发射出去，这就是开始的时候粗率，而最后有所节制。 
且张弓不然：伏檠一日而蹈弦，三旬而犯机，是暴之其始而节之其尽也。 
That was not how I, Fan Sui, strung a bow. It only took me a day to align it with an alignment tool, and then I stretched the string on it immediately, and it was not until after thirty days that I shot the arrows away. That was a case of being rough in the beginning but discreet in the end.
