Final answer:
The Chinese coordinated group movements with weapons evolved into highly organized military strategies with disciplined drilling and intricate tactics during the Warring States era, reflecting developments in military technologies and organization.
Step-by-step explanation:
The coordinated group movements with weapons that the Chinese practiced as early as the first millennium BC evolved into complex forms of military organization and strategy. These evolved forms manifested during the Warring States era when immense conscript armies, disciplined drilling, and elaborate tactics became essential due to the new military technologies like the crossbow. The transformation from chariot and cavalry-centered warfare to infantry and siege warfare required meticulous discipline and organizational skills, leading to treatises on military strategy and the art of war. Additionally, states like Chu and Zheng excelled in the arts, including styles of dance, which likely shared roots with earlier military exercises focused on coordination and movement.
