In the end, the rich man thought that Xiuer would obey as long as Xiaoer died. So he persecuted him on the grounds of debt, and finally made him jump into the lake and die.
When Xiuer learned that Gui Er had died, she rushed to the lake and wept all day. Time passed day by day and finally turned into a blue mountain. Because this mountain was changed by Xiuer, people later called it "Xiushan" and the lake was renamed "Qiqi Lake".
