Do you know why "fàng gēzi" became a byword for no-shows?
In ancient times, people didn't have cell phones or the Internet, so they used pigeons to communicate. Pigeons were used to carry messages in ancient Egypt around 3000 BC.
China is also an ancient pigeon breeding country. Pigeons were used to deliver letters in guangzhou and other places in southern China. "【Fēi gē chuán shū】Sending messages with pigeons" is also like this.
And "fàng gēzi", the original meaning refers to the release of doves, a symbol of peace. But why do people like to call it standing up?
There are various theories as to the origin of the idea of standing up.
