When airmail became snail mail | 当空邮慢过蜗牛😎 Early this year, I received this envelope in my mailbox. The snail mail kind of physical mailbox. It was a Christmas gift from my manager. I wonder.... who has used this kind of envelop before? Who has seen this kind of envelope before? Or one day will someone ask what is an envelope? 我在我的邮箱里收到这个信封。是那真正摸得着的邮箱不是电邮。这是我经理送来的圣诞礼物。不知道....谁使用这种信封？谁见过这种信封？或者有一天会有人问啥是信封？ #Singapore
