I am a rural hukou in Hunan, and now I work in Changsha. Companies can buy social security. Do you think I should buy it? What benefits can I get from buying it? in time

Yes, especially if you work in the province. If you have bought it for several years and need to support other places, you can also transfer there. You can continue to buy in your own name in the future. When you retire, the pension salary will be calculated according to the number of years you have bought in various places, because the average salary in the first area is different. It is generally understood that if you pay higher monthly pension insurance than your hometown, your retirement salary will definitely be higher than your hometown. I bought it for nearly 10 years, and I bought it in other provinces. In a word, buying old-age insurance is also the economic guarantee after you get old.
