There is a very old story about two sisters. Although my sister is blind, she happens to be good at weaving, diligent in managing the family, and lives a very down-to-earth life. Although my sister is smart and healthy, she is lazy and neglectful of the family, and lives a very miserable life.

Whenever there is no food to cook, my sister goes to my sister's house to borrow some food. When she borrows food, she takes a basket with the mouth facing up and fills it with food, so that my sister can touch it with her hand to confirm how much she borrowed. When returning the basket, the mouth is deep and the bottom is shallow, and it is also full of food, so that my sister can touch it with her hand to confirm that she still has enough. In fact, she used this method to deceive her sister and take advantage of her sister's whole life.

Later, my sister died peacefully. When my sister was going to die of old age, she recalled what she had done all her life, and suddenly woke up. She felt that she was ashamed of her sister and conscience, and could not close her eyes after death.

The story didn't end here. In the next life, my sister gave birth to a hen, went to the wild every day to forage, and came home to lay eggs for my sister, one a day, without interruption. A few years later, when Khan tried his best and could no longer lay an egg, facing my sister's family, the hen suddenly spoke: "My sister owes my sister decades." After saying that, she quietly closed her eyes.

This story tells us never owe others. When you owe others, you also owe your conscience. When you owe others, they may not know it, maybe they know it well but don't care. But your conscience will be uneasy from time to time and torment you all your life.
