One tale of the folklore is about an elderly couple with a precious son. On the night of New Year's Eve, since they were afraid that "sui" would come, they took out eight pieces of copper coins to play with their son in order to keep him awake. Their son was very sleepy, however, so they let him go to sleep after placing a red paper bag containing copper coins under the child's pillow. The two older children were also stayed with him for the whole night. Suddenly, the doors and windows were blown open by a strange wind, and even the candlelight was extinguished. It turned out to be "sui". When "sui" was going to reach out and touch the child's head, the pillow suddenly brightened with the golden light, and the "sui" was scared away, so the exorcism effect of "red paper wrapped copper money" spread in the past China (see also Chinese numismatic charms). The money is then called “ya sui qian (压祟钱)”, the money to suppress sui.
