Jiangdong.
It is a region conceptualized within this area, located on the southern bank of the lower reaches of the Celestial River of the Great Song Dynasty.
A thousand years ago, the Jiangdong region gradually developed into a prosperous area and became a key financial and tax hub for various dynasties.
At that time, due to great chaos, various forces declared independence on this land and became countries, with the Wu Clan controlling the Jiangdong region and establishing a regime called the Wu Kingdom.
Later, as the country was unified again, the Wu Clan conformed to the prevailing trend and submitted to the unifying emperor of the time.
After two more dynastic changes, the Wu Clan still stood strong in the Jiangdong region, swearing allegiance to whoever held power.
