In 809, along with a number of imperial scholars, led by
Li Jiang, requesting that Emperor Xianzong create a
crown prince, Emperor Xianzong created Li Ning crown prince on May 9. He also changed Li Ning's name to Li Zhou, but soon changed it back to Li Ning. Meanwhile, Li Ning's formal investiture ceremony, initially set for the fourth month of the
Chinese calendar, was delayed initially to the 10th month of the lunar year, and then delayed again, both times due to rain, but finally held in the 10th month. He died just before the
Chinese new year in 812. Emperor Xianzong mourned his death with a 13-day mourning period. As the regulations on imperial ceremonies at the time lacked any regulations on the funeral for a crown prince, he put a professor of the imperial university, Pei Chai (裴茝), in charge of Li Ning's funeral. == References ==
