Companies pay social insurance, that is, five insurances. I am 20 years old now. Is it appropriate to hand it in so early? I still have 40 years to retire. Is it inappropriate?

Of course, buying early is better than not buying at all. First, because social security needs 15 to pay after retirement, you can pay enough years as soon as possible, and it will be easy in the future. If you want to pay more for a few years, you can get more money after retirement. If you pay 15, you can save the money if you don't want to pay it. Second, the payment base of social security is rising every year. The more you pay next year, the more you pay, but your retirement age is fixed. At that time, your pension will be paid according to the average income of employees at that time, that is, the sooner you pay in full, the less you pay and enjoy the same pension base. Third, it's best to hand it in early while you are young, and don't wait until middle-aged unemployment and other unpredictable times, okay?
