He Jingying's father He Ji was a high-level official during the reigns of Xiao Zhaoye's great-grandfather Emperor Gao and grandfather Emperor Wu of Southern Qi. Her mother Lady Song was He Ji's concubine. He Ji's wife Liu Chuyu the Princess Kuaiji was the daughter of Emperor Xiaowu of Liu Song; later, because He Jingying was adulterous, just as Liu Chuyu was, some historians erroneously reported Liu Chuyu as He Jingying's birth mother, but that was not true.
In 484, when Xiao Zhaoye's father Xiao Zhangmaothe Crown Prince was considering whom to take as a wife for his oldest son Xiao Zhaoye, he considered a number of daughters of nobles, and initially he rejected He Jingying on account of He Ji was sonless and therefore did not have a strong household. The prime ministerWang Jian pointed out that since Xiao Zhaoye would be in line to inherit the throne in the future, he only needed a wife of noble birth, not necessarily one with a strong clan. Xiao Zhangmao agreed and took He Jingying as Xiao Zhaoye's wife. As Xiao Zhaoye carried the title of Prince of Nan Commandery, He Jingying received the title of Princess of Nan Commandery. He Jingying was known for her adulterous activities, as she had on affairs with others while she was princess. The most known affair she carried out was with Xiao Zhaoye's attendant Yang Min : it was said that they spent day and night together, just like husband and wife. However, He Jingying was also very loving in her relationship with Xiao Zhaoye and they had a happy marriage, and so Xiao Zhaoye turned ablind eye to the affair. Some historians indicate that there could have also been a sexual relationship between Xiao Zhaoye and Yang Min, suggesting a ménage à trois. In 493, after Crown Prince Zhangmao died, Xiao Zhaoye became crown prince; Princess He became crown princess. Outwardly, he mourned his father's death and was worried about his grandfather Emperor Wu's health, as Emperor Wu was also in ill health at the time, but when he wrote to the Crown Princess, he wrote one large character of Xi surrounded by 36 smaller Xi characters.
Empress
Later that year, Emperor Wu died. Xiao Zhaoye succeeded him as emperor, and he created Crown Princess He empress. He took her family members into the palace and set up quarters for them in Yaoling Palace - a major breach of protocol at the time. As empress, Empress He continued her affair with Yang Min. In early 494, Xiao Zhaoye's granduncle, the prime minister Xiao Luan sent the trusted general Xiao Tanzhi to advise Xiao Zhaoye to execute Yang Min, and initially, Xiao Zhaoye refused, and Empress He tearfully pleaded for Yang's life. Xiao Tanzhi, however, pointed out how the news of the affair between Empress He and Yang had become widespread. Xiao Zhaoye was forced to agree, and he issued an edict for Yang's execution. When he subsequently tried to withdraw the verdict after Xiao Tanzhi left, it was too late; Yang had been executed. In fall 494, with Xiao Zhaoye despising Xiao Luan for his constant curbing of his activity, Xiao Luan became apprehensive, and he assassinated the young emperor, posthumously demoting him to the title of Prince of Yulin. Empress He was demoted to the title of Princess of Yulin. Nothing further was recorded in history of her activities or the date of her death.
