What was the Iron age of china?

The Iron Age in China, which began around the 6th century BCE and lasted until approximately the 3rd century CE, marked a significant period of technological and cultural development. During this time, iron Metallurgy advanced, leading to improved agricultural tools and weapons, which contributed to increased agricultural productivity and military effectiveness. The era saw the rise of powerful states, particularly during the Warring States period, and laid the groundwork for the eventual unification of China under the Qin Dynasty in 221 BCE. Additionally, this period was characterized by philosophical developments with the emergence of Confucianism and Daoism.
