【答案】Dear Sam，
I am so delighted to receive your e-mail.Learning that you are interested in Alipay，which has recently taken our country by storm，I'm writing with pleasure to briefly introduce it.
Alipay is a software of electronic payment that can transfer the money from your deposit card into the application so that you are able to pay for commodities using your phone.It is the widespread use of Alipay that saves us the trouble of taking cash.
For my part，I'm in favor of Alipay in which we can purchase stuff in a more convenient way.However，personal information could be revealed，so we need to use it properly.
I would be delighted if the above could be of value.If you want to know more，feel free to ask!Looking forward to your reply!

Yours，
Li Jin
