The coins of the Seven Heroes of the Warring States Period: Qin, Chu, Qi, Yan, Zhao, Wei, and Han were composed of four types: cloth coins, knife coins, ring coins, and ant nose coins (grimace coins). They were the four major monetary systems during the Warring States Period.

The cloth coin, in the shape of a shovel, evolved from the agricultural tools "money" and "money" used in the farming economy. This is why the currency is called "money". "Bu" is a borrowed word for "镈". The circulation scope of cloth coins is mainly in the agricultural economic areas in the middle reaches of the Yellow River, such as South Korea, Zhao State, Wei State, Yan State, etc.

Knife coins, knife-shaped, originated from fishing and hunting economic tools. Mainly circulated in the eastern vassal states in the Yellow River Basin such as Qi State, Yan State and Zhao State. The sword coins of various countries are of different sizes and shapes. Among them, the sword coins of Qi State are the most simple and exquisite.

Round money, a round hole, is also called ring money. The spinning wheel or jade ring, which originated as an economic tool in the handicraft industry, was mainly circulated in the Qin and Wei states. After the middle period of the Warring States Period, Qin was the first to adopt round coins with square holes, and later Qi and Yan also followed suit.

Ant-nosed money, also known as ghost-faced money, is a copper coin with inscriptions from the southern Chu State. It is irregularly oval in shape and has inscribed inscriptions on it. One type of money has inscriptions that look like ants crawling on a person's body. The one on the bridge of the nose is the same, so it is called ant-nosed money; the other one looks like an ugly ghost face, so it is called ghost-faced money. The value is measured in pieces, which is more convenient to use.
