Firstly, the heir to the Zhao throne was required to spend a large portion of his youth as a hostage in the Qin court – thus making him susceptible to court intrigue.
The famous Zhao general Lian Po objected to this state of affairs and resigned his posts as a result.
King Daoxiang's rule saw the Zhao state engage in warfare with its eastern neighbour, Yan.
After Jia had lost favour with Daoxiang, Qian was established as the new heir apparent and Zhao Mianchang was installed as the new queen.
[2] King Daoxiang appears in manga and anime series Kingdom.
