Some problems about Chinese bronzes and Japan and South Korea

1, whether bronzes were introduced into Japan and South Korea is not recorded in history, but is archaeological speculation. China invented iron in the Han Dynasty and abandoned bronze ware. At that time, there were no words in Japan and South Korea, so it was impossible to form a record.

Before the invention of iron smelting technology, people can only make tools with bronze, which is much better than tools made with stones and sticks. Therefore, in international history, a nation can only be said to have entered the era of civilization if it has mastered bronze technology. At that time, people used bronze to make farm tools, tools, weapons and household utensils. After the invention of iron, bronze was only used to make sacrificial utensils.

In Dayu era, Jiuding was cast as a symbol of Kyushu, and it has been handed down as a symbol of political power since then. Although Japan and South Korea are affected, they don't feel like China.
