Here’s how red envelope giving is broken down during Lunar New Year, from lucky amounts to properly accepting your blessings.

Lunar New Year is just around the corner and there is one tradition that everyone is excited for. Red envelopes, or li xi in Vietnamese, hongbao in Mandarin and lai see in Cantonese. These red packets are filled with cash and good luck and today we will break down the math that’s inside. 

Let’s start with who gives red envelopes? Usually they are given by parents and older relatives to younger children and other family members to pass on good luck for the new year. So if you marry into a family that celebrates the New Year, consider yourself officially part of the group of givers. Red envelopes can also be extended to employees, friends, and service workers as a sign of appreciation and blessings to come.

Now let’s talk numbers because there is a strategy behind how much cash goes into each envelope. Amounts increase based on age and relationship to the receiver. Young kids and acquaintances often get smaller bills, but a true red envelope giver will place a lucky $2 bill inside as a more symbolic gift. Teens and college students may receive bigger bills like tens and twenties depending on how close the relative is. 

While it is not required, it is common to show parents and grandparents respect and gratitude as well during the New Year. Generally once you are financially independent or married, presenting a red envelope to your elders is seen as a way to wish them longevity. When giving one to an elder, it is common to place one or two hundred dollar bills inside. 

Beyond the bills themselves, the exact number value can also matter just as much. Numbers ending in 6 or 8 are associated with wealth and prosperity and numbers like 4 are to be avoided as it can sound similar to the word for death in some Chinese dialects.

If you are receiving a red envelope this year, remember to always accept it with both hands and return the New Year’s wishes back. It is also considered rude to open up your red packet in front of the person who gave it to you because at the end of the day it isn’t all about the cash, but rather those who are sending good fortune into your year ahead.
