► Chu (south): The State of Chu was in the south along the Yangtze. It had the largest land area but much of this was undeveloped frontier.
Others: On the southeast coast near Shanghai was the minor State of Yue. In the far southwest in Sichuan were the States of Ba and Shu. These were non-Zhou states that were conquered by Qin late in the period. Between Shandong and Shanxi (literally ‘Mountain-east' and ‘Mountain-west'), that is, between Qi and the Three Jins, was the central plain with its dense population and many small states.
