Original text:
One's ancestors should always benefit future generations. However, those who can benefit from fruits are fresh. Why is there still a long way to go? Today is the mastermind of later generations, but it is widely used to make a living. Tian Chou is connected to the building, the mansion is separated by the square, millet is full of money, gold and silk are full of money, and what he wants is not enough. Shi Shiran thinks that his children and grandchildren can use it all the time. However, I don't know how to cultivate my son's righteousness and make his family polite. After decades of hard work, my children and grandchildren wandered luxuriously between the ages, laughing at their grandparents' ignorance of self-entertainment, complaining about their meanness and ingratitude to me, and severely abusing them.
