This statement has no scientific basis and is a superstitious tradition. In the traditional custom of putting chopsticks under the pillow for the first three days, the head of chopsticks usually means "good luck", while putting chopsticks under the pillow is considered to have the function of exorcising evil spirits and praying for blessings. However, this statement has no scientific basis. Putting chopsticks under the pillow for three days can not only change people's fortune, but also cure diseases or bring good luck.
Therefore, we should treat these traditional customs rationally, not blindly superstitious, and pay more attention to scientific knowledge and practice.
