A red packet or a red envelope is a monetary gift given during holidays or for special occasions such as a wedding. --- Wikipedia

In Taiwan, for guests attending weddings, the customary red envelope gift typically starts at NTD 600. When estimating a total gift amount of less than 10,000 NTD, it is advisable to steer clear of the numbers 4 and 8. This caution stems from cultural nuances, where the number 4 is associated with the word for "death," and the number 8, while considered “wealth” in many contexts, sounds similar to the word for "separation." Thus, it may not be deemed suitable for inclusion in wedding gift amounts. Additionally, one should avoid having an odd digit, which related to funerals, or the digit 0 in the hundreds place, following established conventions.

Interestingly, the amount of NTD 9,900 is considered especially auspicious. This is due to its homophonic sound "jiu-jiu" in Mandarin, symbolising a heartfelt wish for enduring marital happiness.

In the event that the gift amount exceeds 10,000 NTD, it is recommended to minimise the presence of two or more odd digits and to avoid the numbers 4 and 8 whenever possible.

However, regardless of the size of the gift you present, the most crucial aspect lies in the sincerity of your well-wishes for the newlyweds. May your contribution be a token of blessings that accompany them on their journey into marital bliss.
