Safety tip: Due to telephone fraud, SMS trap, luring to call back international calls, luring to call back toll stations and other traps, please answer and call back carefully when encountering strange calls. If you use a toll-free phone/mobile phone, you can answer it at will and ask the source of the other party's phone. If you need to call back, you'd better use a public phone without knowing the details of the other party. Don't believe in winning prizes, impersonating acquaintances, impersonating banks, etc. Don't remit money or transfer money to strangers before you fully identify yourself, and don't disclose your bank account number and password.
