It is the expression of the times. "One thousand yuan can buy" means that I am full of love for what I bought at 1000 yuan, which is really useful to myself or can comfort these hearts. At the same time, it can also show the personality of our young people. "Ten dollars must be saved" means that you must spend what you are willing to spend, and you must not spend what you don't need. A thousand dollars can buy ten dollars, and frugality may be the characteristic of our generation.
