Red envelops are an ancient Chinese tradition! The color Red in Chinese culture invokes the power of Joy and Happiness. The color Red is auspicious, lucky and therefore it is used for happy occasions. Red is also the color with the most Yang energy. It can prevent evil, inauspicious Qi or inauspicious events from occurring. Coins can be placed in a red envelope and taped under the computer at work, or taped onto the cash register to bring in money and luck.
