In the Lunar New Year celebrations, "red envelope" has become the key word between friends and relatives. In recent years, due to the rapid development of network communication and the change of real life style, we in China have unconsciously formed a unique red envelope culture, which has a great influence on interpersonal communication. Under the condition of retaining the traditional meaning of red envelopes, a new red envelope communication method of contemporary people has been formed, which is the present red envelope culture. Similarly, red envelope culture can be divided into three categories because of different regions and online life: profit culture in Cantonese, red envelope culture in Mandarin and virtual red envelope culture on the Internet.
