Who is Wu Meiniang's sister in "The Legend of Wu Meiniang"?

My name is Wu Shun, Wu Zetian’s half-sister.

Wu Shun first married Helan Yueshi and had a son, Helan Minzhi, and a daughter, Helan clan.

Because Wu Zetian was in the palace, Wu Shun often went in and out of the palace and committed adultery with Tang Gaozong Li Zhi.

His daughter Helan also followed Gaozong, and the mother and daughter were married to the same master.

The death of Mrs. Korea (not certain) is said to be due to illness. Some say that she was jealous of Wu Zetian because of her relationship with Emperor Gaozong, so she killed her. Some say that Mrs. Korea was killed. Because Wu Zhao learned about Gaozong's affair, he was furious. However, out of concern for his sisters, he planned to send her out of the palace and away from Chang'an. One night, he came to Wu Shun's palace and angrily scolded his sister. Before leaving, he said He said: If you hadn't been thinking about your fellow sisters, you would have ended up like the Wang family and the Xiao family. I should be content with letting you live. After leaving, the Korean lady cried loudly. She also knew that her sister would not forgive her, so she committed suicide in the palace that night.
