If you are from Zhengzhou and work in Hangzhou, you must pay social security in Hangzhou, because Hangzhou has a developed economy, a high payment base and a high pension after retirement. If you pay the same social security in Zhejiang and Henan, if the payment base and grade are the same, and the payment period is the same, such as 15, then the difference between Zhejiang's retirement pension and Henan's retirement pension is at least within 300 yuan. Moreover, the longer the payment period, the more the difference. Because Zhejiang Province is an economically developed region, its consumption level is higher than that of Henan Province, so its retirement pension is also higher than that of Henan Province.
