     Today I’m going to talk about something about e-hongbao that is becoming popular in China. E-hongbao is actual a kind of lucky money from and to relatives and friends during festivals or on some special occasion. For many young people grabbing e-hongbao on their mobile phones is a fairly common and exciting activity. Unlike the tradition of elders give lucky money to their children over half of the people sending e-hongbao is in their 20s. It’s just for fun and the sum of money mattered little. In word e-hongbao is bringing new color to the old tradition. Nevertheless I’m interested with the safety of online payment. It’s hoped that whether rules and regulations should be improved about the e-hongbao system to guarantee their operation.
