Between the seventh and sixth centuries a four-way balance of power emerged between Qin (west), Jin (west-center), Chu (south) and Qi (east) whilst a number of smaller states continued to exist between Jin and Qi.
Antara abad ketujuh dan keenam keseimbangan kekuatan empat arah muncul antara Qin (barat), Jin (barat-tengah), Chu (selatan) dan Qi (timur) sementara sejumlah negara yang lebih kecil terus ada antara Jin dan Qi.
