"He who works hard by the sweat of his brow , enjoys the bread earned by himself and finishes the task on his own efforts without depending on God or ancesters, is really a true man! ” It is a teaching of Zheng Banqiao to his son, which was written on the paper just before his death. It is full of his boundless love for his son and we can see from it Zheng’s cleverest insight. It stresses the importance of independence in the world and extends Love to the height where ordinary people can not understand. Unfortunately, many parents nowadays don’t give proper and enough such moral education to their childrens， although they give them a lot of love and care . 这是郑板桥在生命垂危时给儿子留下的遗训。这遗训寄托着郑老先生对儿子的一腔关爱。我们由此可以看出他目光远大，见识深远。他注重自立于世并把爱心的触角延伸到常人难以体察的高度。遗憾的是，我们当今社会生活中一些为人父母者，在子女问题上，关爱呵护有余，教育引导不足.

Flowing you own sweat, eating yours meals and doing you own things, depending on others,god and ancestor are not good man!
