1, roasted sweet potatoes: Grandparents in the 1960s ate roasted sweet potatoes during the Spring Festival, because rice was very expensive in those days, and the rice at home was limited every month. When there are more people in the family during the Spring Festival, they will share baked sweet potatoes as the staple food of the whole family.

2. Popcorn: Sugar in the 1960s is also very precious, so grandparents will eat some popcorn during the Chinese New Year. The raw material of popcorn is corn. At that time, the yield of corn was very high, so popcorn is a very common snack during the Chinese New Year.
