Dear Peter,

    I'm writing to tell you something about e-hongbao, that is very popular in China.

    E-hongbao is actual a kind of lucky money from and to relatives and friends during festivals or in special occasions. For many young people, grabbing e-hongbao on our mobile phones is a fairly exciting activity. Unlike the tradition of elders give lucky money to children, over half of the people sending e-hongbao is in their 20s. It's just for fun but giving best wishes, while the sum of money matters a little. In a word, e-hongbao is bringing new color to the old tradition.

    Now I'm concerned about the safe of online payment, and rules and regulations needed to be improved to guarantee its operation.

Best wishes.

Yours,

Li Hua
