There were four types of money at that time: knife, cloth, ring and ant knife. (Note: This knife is not USD. Several countries in the northeast of Wei, such as Zhao, Yan, Qi and Zhongshan. Cloth coins. North-south circulation, the Qi and Qin countries on both sides of the east and west don't need it. The Chu countries of Wei, Han, Zheng, Wei and southern Hunan are close to the Zhou Emperor, and the Zhao and Yan countries are north. Huanqian: currency circulating in the north of Chu State. Qin, Zhou, Han, Zhao, Wei, Yan, Qi and other places. Ant nose money: basically, it is dedicated to the state of Chu. This kind of thing is hardly encountered in small transactions. For example, the king of Qin wants to exchange 15 cities for his Cai state, which depends entirely on the strength and willingness of the buyer, rather than winning by weight.

as for gold, it circulates all over the world. Big deals can be met, and not everything can be exchanged between big businessmen! During the Spring and Autumn Period and the Warring States Period, the Zhou royal family was weak and the vassal state was strong, which led to the princes disobeying the orders of the Zhou Emperor and acting in their own way. This has led to a series of problems, and currency is one of them. Currency differences make the conversion between countries extremely troublesome. This is why Qin Shihuang unified the currency after destroying the six countries. Now let me talk about what currencies were divided in the Spring and Autumn Period and the Warring States Period, and how they were converted. Throughout the Spring and Autumn Period and the Warring States Period, Beibi was very popular in various vassal states.

In ancient times, especially before the Spring and Autumn Period and the Warring States Period, the level of productivity was insufficient and the commodity production capacity was limited. Therefore, there is no need and no need to make money. At this time, natural seashells are generally used as money, or only slightly processed. The former is called natural shell, and the latter is called imitation shell. Knife coins are divided into pointed knives and qi broadsword, which are generally considered to have evolved from the handicraft tools "cutting" and fishing and hunting knives. Yan State is located in the north and is greatly influenced by Shanrong culture. Therefore, the shape of Yan sharp knife is very similar to the bronze knife used in Shanrong area. Qi is close to the sea and is greatly influenced by fishing and hunting culture, so Qi's Qi broadsword is similar to fishing and hunting equipment.
