Their original plan was to travel eastward, passing through Wangbei County, Tongling County, Baihua County, Jiangdong County, Yaoshan County, and Yongzhou City, before reaching the border city of Dongyue for sightseeing. Then, they would travel southward, passing through Jiangyin County and Suizhou City, following the Qianjiang Grand Canal to Nanshan County and Wangnan County. Finally, they would pass through the city where Jiangdong County and Wangnan County intersect, which is also only 100 miles away from Wanning City, Yong Chang City.
It was said that Yong Chang City was originally the fief of Princess Yong Chang, but for some reason, Princess Yong Chang did not go to the fief.
Later on, Princess Yong Chang disappeared for no reason. Duke An Manor used the reason that the city could not be left unguarded due to the absence of the princess to take over her fiefdom.
