There is a logo on the back of the red envelope. The trademark on the back of the red envelope will not affect the use of the red envelope, nor will it affect the writing on the back of the red envelope. In the traditional sense, red envelopes are also called lucky money. They are money wrapped in red paper by elders to children during the Lunar New Year. It is said that during the Ming and Qing Dynasties, most of the New Year's money was given to children strung with red strings. After the Republic of China, it evolved into wrapping with red paper. It generally refers to a red paper bag containing money, which is used as a gift during festive occasions, and also refers to money used to bribe others. In the Cantonese-speaking area of ??China, red envelopes are called profit, and they are a gift made by placing money in a red envelope.
