"棍棒之下出孝子"如何翻译为英文？

中国人信奉"棍棒之下出孝子"，西方社会同样的说法是：
Spare the rod, Spoil the child.

如果非要表现出孝子，那么可以用：
1.where there is a strict supervision, there is a dutiful son.
2.Practice makes one perfect, while rod makes one dutiful.
3.It is the strict rules that give birth to filial piety.

棍棒下出孝子:
Spare the rod spoil the child.
英语中刚好是这个谚语对应的

spare the rod and spoil the child.
就这个最接近啦，英美国家人没那么注重 “孝”，所以人家不讲“孝子”

spare the rod, spoil the child
中国人信奉"棍棒之下出孝子"，西方社会也有类似的说法
