In fact, I think if you have relatives or friends who are getting married and don't know how many red envelopes to pack, you should refer to the customs of your hometown or the local customs of the married person to decide how many red envelopes to pack. After all, the cultural customs of each place are different, so we can't benchmark the customs of other places, otherwise it will be embarrassing sometimes. Originally, you kindly took a red envelope to bless you, but it turned out to be self-defeating, which is not good. Just like our custom here, the money that comes with gifts is still average, neither more nor less. For example, some places in Fujian do not need to wrap red envelopes for other people's weddings and other activities, or the number of bags is very small. For example, dozens of pieces are already a lot, unlike hundreds here. So in this case, you should do it according to the local customs of the other party. For example, if your friend is from chaozhou people, Guangdong Province, and you don't have the custom of wrapping red envelopes or the number of red envelopes is very small, then when you want to wrap red envelopes for your friends, you can't follow your custom of not wrapping red envelopes or wrapping dozens of dollars, which will make the other party feel that you are very strange and don't understand secular customs at all, and vice versa.
Therefore, it is also a science for others to get married and seal red envelopes. Remember to do it according to the local customs of the other party, not according to the customs of your hometown. Otherwise, sometimes you may offend people and you don't know it.
