Because white things can't be packed with happy events, they are usually packed with plain paper and white paper, and white envelopes are often used. So red envelopes of other colors are suitable for red things.

The cover of the red envelope is beautifully printed. In addition to the traditional red color, there is also a golden envelope with many patterns on it. In addition to the auspicious patterns and zodiac patterns printed by plane printing and bronzing, there are also three-dimensional laser printing and cartoon characters.
