A banknote from 46 years ago, a college entrance exam admission ticket from 16 years ago. I have a collecting hobby and was rummaging through my family’s treasure chest. I found a stack of train tickets from my university days, but the writing on them has been faded by time. The New Year’s money from when I was a child, I surprisingly still have it, which is now 46 years old. That 2 yuan bill was from when I visited relatives during the New Year, and even though they were giving red envelopes to their own relatives, they also gave me 2 yuan.
