Jill, the son of Liu E in Song Gong Ci, died after being sent to Liao as a proton. Liao signed a Covenant with the Northern Song Dynasty, and the Northern Song Dynasty sent protons to Liao. Another woman knelt in front of Zhao Heng with her son, crying like a pear flower with rain. Zhao Heng relented and promised not to let their son do protons.

After meeting Liu E, he said that he would give Jill to Liao. Liu E cried very sadly. Jill saw Liu E like this and asked Zhao Heng what had happened. Zhao Heng repeated what he had just said. Jill didn't want to leave Liu E, so she hugged Liu E and wept bitterly. Later, under the persuasion of Zhao Heng, Jill went to Liao country, and then died unexpectedly on the way to Liao country.
