在中国，传统的红包只出现在春节和婚礼上。

2014年中国春节首发微信红包。

数据显示，2016春节期间，超过4亿人送出或接收大约80亿个红包。

In China，cash gifts are traditionally given in real red envelopes during weddings and the Chinese
New Year．The WeChat red envelope was launched during the 2014 Chinese New Year with a stipulation(规定)that the amount should be less than 200 yuan．Figures from Tencent Holdings Ltd．(腾讯控股有限公司)show that during that festival period，about 8 million users snapped up 40 million red envelopes．
For example，if a person in a WeChat group of 10 sends 100 yuan as a gift and says any one can have a maximum of 20 yuan，the first five to “grab”get the money while the other four miss out．Red envelopes add a sense of atmosphere and strengthen interaction．The amount everybody gets could be different，so it is funny to see the comparisons．
During the 2016 Chinese New Year's Eve，more than 420 million people gave or received the envelopes and about 8 billion red envelopes were sent out that day，eight times the figure for the last year's eve．
The WeChat red envelope is an innovative(有创意的)way for people to send greetings．It also gets people into the habit of using WeChat payment，because you need to link it to your bank account．For Internet companies，functions such as WeChat payment are an important part of the whole Internet ecosystem，as many other functions such as hailing taxis or shopping are based on online payment．
