The ancients said: "Accumulating virtue is better than accumulating money, and buying books is better than buying land." Giving children a sound character is far more important than leaving a huge fortune. In fact, the biggest investment in life is children. Some parents only care about making money, but fail to educate their children well. As a result, the money they earn for a lifetime may be squandered by their children in one or two years. If the children are well educated, the money that parents earn for a lifetime can be earned by their children in one or two years.
