Zhang Xipin used her princess status to recruit cronies in North Korea, which caused widespread indignation and dissatisfaction. When Su Zong saw it, he began to hate it and miss Queen Inhyeon more. 1694, Zhang and his brother Zhang Xizai tried to poison, but Su Zong caught them and got rid of a group of rebels. This move added to Su Zong's nostalgia, so he returned to the palace on April 27 of the same year, re-established the queen, and reduced Zhang to a concubine. Zhang was deeply dissatisfied with this. After many unsuccessful appeals, he secretly asked the wizard to harm him.

Later, it was discovered that in 170 1 year, Su Zong deposed Zhang Wei and poisoned him on charges of "cursing the king" and "demon princess".
