I received a phone call from a scammer when I was a student in university . He told me I had a package to receive but it was taken by a policeman because of carrying illegal stuffs . He taught me how to handle it by finding an ATM and inserting my bank card to recognize the real me and clarify it had nothing to do with me. I was really scared at that moment , because I was young and lacked of experience to deal with this. Fortunately , I talked about this to my roommate and they told me it was a scam so I wasn't scammed finally and kept my money . Nowadays in society , scammers are much smarter with various of tricks and deceptive methods by acting fake emotions . Even in China , people always think it's very safe around them .
