Wechat is very popular nowadays, even the foreigners are crazy about this communicative tool. The functions of Wechat are various, such as talking to friends and paying the bill. One of the hottest functions is to send red packet. If people want to catch everybody’s attention in the group talk, sending a red packet works well. Everybody is excited to share the money and they will feel lucky if they get the money. This function brings happiness and I love it so much. Sometimes when I hear the voice, I will open the phone and try to get the money as soon as possible. When I open the red packet, I will be very happy.
