In the Han Dynasty's Miscellaneous Notes on Xijing, it was recorded: "Those who are full use soil as a tool to store money. If they have in-depth experience but no out-of-body experience, they will pounce when they are full. " The piggy bank has an entrance but no exit. The ancients often used this as a metaphor for being a man. People are too greedy to get in or out, so they have to give up. In the end, it will only "pounce on it when you are full" and end up in ruin.
Let's talk about how the ancients saved money. Because most of the coins in circulation at that time were copper coins, there was a piggy bank in ancient times with an interesting name. This is a pot-shaped or box-shaped utensil made of pottery. There is a narrow opening at the top to put copper coins in, and scattered copper coins in. Generally, there is a small eye in the abdomen for inserting a rope, which is usually hung on a beam. In ancient times, thieves were called "gentlemen on the beam"
It was popular to hoard silver in the Song Dynasty, because the hoarder didn't easily disclose the location of the money, so that the house changed hands. When the new owner renovated or rebuilt, he often found the previous hoard of silver and picked up a big bargain.
In the Song Dynasty, Shen Kuo recorded in Meng Qian's Bi Tan: "In Luo Zhong, there are many places to stay and hide, and those who have land will dig for money." It means that some old houses have been sold, so we have to add some money to dig them, because it is likely that the cellar will be dug out.
