The Reign
Zhao Dun came to the throne in 1189, when his father abdicated and retired. He was already in his forties, and his health, both physical and mental, was poor. Much of the real authority at court passed to his wife, Empress Li.
Empress Li
At first Guangzong regularly attended his father at banquets and on excursions, as filial custom required. That changed under the influence of Empress Li (Li Fengniang), whom the traditional histories portray as jealous, shrewd and ruthless. She came to dominate the government through her husband, and he has been remembered as a weak ruler under his wife's control.
In 1191, according to the histories, the empress had the emperor's favourite, Consort Huang, killed while he was away from the palace. The shock left Guangzong ill and confined to his bed, and the empress took charge of state business herself.
She also worked to keep father and son apart. Xiaozong had rebuked her sharply for her conduct, and she told Guangzong that his father meant to have her removed. When Xiaozong sent medicine for his son, she suggested that it might be poisoned. From then on Guangzong found excuse after excuse not to visit the retired emperor.
Southern Drama
Guangzong's reign is associated with the beginnings of nanxi, the "southern drama" of the Wenzhou region on the southeast coast, one of the earliest forms of Chinese opera. One early account dates its origins to his reign, although other writers place them earlier. Nanxi combined local folk songs, ballads and sung stories with the older traditions of mime, dance and song, used everyday language, and told its stories in long sequences of scenes.
