The Legend of Yung Ching

The assassination of Kangxi during the magnificent "Hunting Exercise of Autumn" sparks off a bloody struggle for the throne. Kangxi orders his fourth son, Prince Yong (Chinese: 雍親王) (Yinzhen), to investigate. Yinzhen disguises himself as a trader in Jiangnan. He meets a famous scholar's daughter named Lu Sisi (Jade Leung) and, after overcoming various obstacles together, they fall in love. The show shows how Yinzhen's scheming and plotting allowed him to finally become the Yongzheng Emperor.
