"It is inevitable to use a copy of your ID card in your life. Citizens should properly keep a copy of their ID cards and don't disclose their information to strangers. " Chen Xue reminded that the general public should take good care of their personal information when handling related businesses, especially when using copies of personal ID cards through the Internet or intermediaries, so as to prevent these documents from falling into the hands of criminal suspects and becoming tools for them to commit crimes. At the same time, when using personal credit cards, citizens should also keep them properly to prevent them from being forgotten in public places such as ATMs and banks. Don't lend your credit card to strangers. If you lose your credit card, you must apply to the bank for loss reporting at the first time to prevent personal property from being infringed.
