To avoid risks, some important things you need to keep in mind when using WeChat Wallet (or Alipay and other online payment options).
Check strangers'identities
Be cautious when adding strangers to your contact list, as it increases the risk that your bank account can be hacked and wiped clean. Defrauders can also steal your name and profile picture, and then add your friends using a fake account. You will never find out, because you're blocked. So warn your friends if the fake "you" intend to borrow money from them.
Change your pin regularly
Change your pin as frequently as possible, especially if you are using your wallet account regularly. Avoid using birthdays, names, and other personal indicators.
