Because the ID card has a maximum certification period of three months, it has to be processed three months in advance, just as the new card has to be completed, and the old card will be handed in after the expiration, so as not to delay the use. If the old card expires, the new card will not come down, which will delay the use.
People's Republic of China (PRC) Identity Card Law

If a resident identity card is lost, it shall apply for a replacement.
