Who has the happiest childhood after 70, 80, 90 and 00?

Speaking of living standards, the material conditions after 00 are of course the richest, but the happiness of childhood seems to be not necessarily related to material conditions and living standards! Because happiness means being happy, happy, happy and comfortable, and leaving a deep impression in your mind, people of all ages have very happy and unforgettable moments in their childhood. I was born in 46 years, and the conditions in the early days of liberation can hardly be compared with now, but at that time, there was a wooden camel, an iron ring and a "pen" cut from bamboo, which was also very happy and unforgettable!
