A red envelope or red packet () is a monetary gift given during holidays or for special occasions such as a wedding, a graduation, or the birth of a baby. Although the red envelope is from Chinese traditions, other cultures also share similar traditional customs. The red packet is also called "money warding off old age" () for Chinese New Year.
These customs have also been adopted across parts of Southeast Asia, and other countries that have a sizable ethnic Chinese population as well. In the mid-2010s, a digital equivalent to the practice emerged within messaging apps with mobile wallet systems localised for the Chinese New Year.
Red envelopes, more commonly known as Hong Bao (in Mandarin) or Lai See (in Cantonese), are gifts presented at social and family gatherings such as weddings or holidays such as Chinese New Year. The red color of the envelope symbolizes good luck and is a symbol to ward off evil spirits. It is also gifted when a person is visiting as a gesture of kindness for visiting. The act of requesting red packets is normally called () or (), and, in the south of China, (). Red envelopes are usually given out to the younger generation who are normally still in school or unmarried.
The amount of money contained in the envelope usually ends with an even digit, in accordance with Chinese beliefs; odd-numbered money gifts are traditionally associated with funerals. An exception exists for the number nine, as the pronunciation of nine () is homophonous to the word long (), and is the largest single digit. Still in some regions of China and in its diaspora community, odd numbers are favored for weddings because they are difficult to divide. There is also a widespread tradition that money should not be given in fours, or the number four should not appear in the amount, such as in 40, 400, and 444, as the pronunciation of the word four () is similar to the word death (). When giving money, new crisp bills are normally given instead of old dirty bills. It is common to see long queues outside of banks before Chinese New Year with people waiting to get new bills.
