Because of the family situation and the previous experience of the elderly, they have developed a habit of thrift. Just like some old people have enough money at home, but she will still pick it up. She was reluctant to spend money and earned some money, which she would give to future generations on an important day or one day. In fact, future generations do not want her to be like this, but she is still like this. I wish these hardworking and caring old people happiness in their later years.
