Your PC is so amazing . Are you doing trade on internet ?   Thank you for your compliment . I bought this PC with my first-month salary . I am getting to know the on-line trade .   I'm wondering if you often trade with others on the internet .   Yes , I often do business through internet now .   Oh , really ? Is it a good way ?   Yes , very gorgeous . Sometimes , I can deal with my business without stepping out of our house .   What advantages does it have ?   Firstly , it is convenient . And secondly , it has low cost , because you know you only need to pay the fee of internet service .   I agree with you . It will cost too much when going abroad to join the exhibition .   The most important is that it is very convenient . You know you can browse the website and send E-mails to your customers at any time . Even you can have e-contract with your regular customers .   So cool , if we do business through other ways , it will cost a lot of time .   Sure , but every coin has two sides . Doing business through the internet is not as safe as doing business through traditional ways .
