Yu Xiu's plan to have Xianzhu take the place of the real Yu Xian'er at Taisu Sect. Both girls were seventeen, and since Taisu had never seen the real princess, Yu Xiu presented Xianzhu as the child of an old friend at Immortal Shangyong's birthday banquet. The scheme succeeded: Xianzhu entered Taisu as Yu Xian'er and became the beloved disciple of the Sect Master, while the real Yu Xian'er was turned away eight miles from the gate.
