I accidentally lost my ID card, so I have to reissue it. Is the original invalid or still usable? Online said to report the loss. Can you tell me if you understand it? no

Reporting a loss in a newspaper (usually a local mainstream newspaper) is to prevent others from doing bad things with it. According to the relevant laws and regulations, after you report the loss in the newspaper, it means that you have fulfilled a wide range of notification obligations. The relevant responsibilities caused by the notice have nothing to do with you, but belong to the audit obligation of the relevant person or unit when using it.

Take your new certificate or the certificate issued by the public security household registration to the newspaper office to declare the loss report invalid.
