What is the relationship between Li Shimin and Yang Guang?

The relationship between Yang Guifei and Li Shimin was twofold. Yang Guifei was both Li Shimin's granddaughter-in-law and his great-grandson's daughter-in-law. At first, Yang Guifei was the wife of Emperor Xuanzong's son, King Shou. Because of her beauty, she became Emperor Xuanzong's concubine. According to the information provided, Noble Consort Yang's background was rather complicated. She was born into an aristocratic family of officials and was once conferred the title of Princess Shou. However, due to the death of Emperor Xuanzong's mother, Concubine Wu Hui, Emperor Xuanzong became interested in the beauty of Concubine Yang and married her as his concubine. Therefore, after Emperor Xuanzong of the Tang Dynasty deposed Empress Wang, Yang Guifei was equivalent to an empress. In short, Yang Guifei was Li Shimin's great-great-granddaughter-in-law and later became his great-grandson's daughter-in-law.
