My informant is a student who was originally from China but came to study in US since high school.
“You know, red pocket money is one of the biggest tradition during Spring Festival in China. But in my family, not only we get red pocket money from people much older than us, we also put them under our pillow at night. It’s like really coordinating with the word “压”(push down) in “压(push down)岁(age)钱(money)” (red pocket money). And my grandparents would also put ivy leaves inside there, just for good luck.”
“I know they are many superstitions from Chinese family, especially my family haha. But we still do that, I don’t think the truth matters that much in this case, I like these traditions.”
I think it’s really interesting that in both asian and western culture we have this kind of gift thing for kids during important festivals. Hoping for good luck with ivy leaves inside red pocket money that placed under their pillow to Chinese children, waiting for christmas gift to be put inside the christmas sock for western children, they both serve as a good method to give them hope and believes; as well as for better sleeping quality since they all happen during bed time.
