In addition to embodying the Chinese people's emphasis on ritual exchanges, the red envelope culture also includes those who receive benefits and do not forget to give, and also have a mentality of not daring to be ungrateful. On the seven continents of the world, wherever there are Chinese people, the red envelope culture exists and flourishes. When Chinese living overseas return to their hometowns to worship their ancestors, they routinely send red envelopes to relatives and friends. Because people are close and distant, and the gift points are thick and thin, the red envelopes sent out are divided into three categories: large, medium and small. It is also a feature of the red envelope culture to see whoever sends a red envelope.
