《汉书·传·萧何曹参传》
萧何买田宅一定在贫穷偏僻之地，治家不修有院墙的房屋，说： 假使后代贤能，将学习我的俭朴；不贤，也不会被权势之家所侵夺。 
何买田宅必居穷辟处，为家不治垣屋。曰： 今后世贤，师吾俭；不贤，毋为势家所夺。 
When Xiao He bought fields and houses, he made sure they were in poor and remote areas. He managed his household without repairing the walls of his house, saying: If my descendants are virtuous, they will learn from my frugality; if they are not virtuous, they will not be encroached upon by powerful families.
