The second purpose is to bring good luck. We wish each other a smooth and safe life during the festival, which is a good wish. For those who can't handle things smoothly for a period of time, you can put money under your pillow to get rid of bad luck and bring good luck to your life. Putting money under the pillow, people sleep under pressure and stick close to each other, which is a symbol of good luck and means that life is very auspicious. This money can take away people's discomfort and bad luck.
The third purpose is to become rich. For most people, living a rich life is a lifelong goal. They also draw lots in their lives and burn incense in temples. Everything is for the safety and prosperity of their family. This is everyone's dream. Putting RMB under the pillow is a way to pray for becoming a rich man, which is the same as wishing to put money under the pillow. I hope to have a family that can give money.
