Thank you for inviting me. There are many reasons. Some people were afraid of living in poverty in those years, some got into the habit of scrimping and saving, some prepared to treat the bottom pad for future illness, and because of different consumption concepts, they were really afraid to spend money. It is their fine tradition to live frugally, but some people don&;t have much pensions, and their consumption level is not low. My sister&;s shoes are always tight, and they can&;t wait for the pension every month. Without a good plan, as the saying goes, having enough to eat and have enough to wear is not enough to plan for a lifetime. To sum up, it is a common fault that many old people are reluctant to spend money. They have experienced many complicated things, know that money is hard to come by, and save planned consumption. They have a natural and man-made disaster at home and don&;t ask others. This is their concept. Compared with young people, they have a certain distance and can&;t keep up with the needs of social development.
