I've found this short and clear video that demonstrate how you can cut a fish using only 1 red packet (Ang Pow)
This Ang Pow fish is simple and easy to make that you can teach your kid to do. When your kids have collected their Ang Pows and saved the money, you can get them to recycle those red packets to decorate your house, by doing this simple handicraft.
What you need is just one red packet, a scissors, and a stapler. You can get a marker to draw the eyes of the fish.
A gentle reminder to your kid to be careful when they are handling with scissors.
