I am in Dali, and paying medical insurance online shows what happened to Tengchong.

The social security you paid in Tengchong has not been cancelled, but it can be transferred to Dali to increase your social security payment period, which will help you get a pension in the future. However, there is no need to rush to handle social security transfer and merger now. China social security network, the transfer procedures are much simpler than now, do not have to run back and forth.
