The prequel of "Baolian Lamp" provides a detailed introduction to the plot: Jade Emperor's sister Yaog姬 secretly married a mortal scholar named Yang Tianyou, and they had three children: Yang Jiao, Yang Jian, and Yang Chan. When the Jade Emperor found out, he sent the heavenly army to kill Yang Tianyou and Yang Jiao, and imprisoned Yaog姬 under the Peach Mountain. Yang Jian and Yang Chan narrowly escaped with the help of Nezha and Marshal Tianpeng. From then on, Nezha and the siblings Yang Jian and Yang Chan became wanted fugitives in all three realms. The heavenly army besieged Chentang Pass, and in anger, Nezha committed suicide to repay his parents for raising him. Grandmaster Taiyi used a lotus petal from the Baolian Lamp to recreate Nezha's golden body. To keep Nezha in check, Grandmaster Taiyi entrusted the Baolian Lamp to Yang Chan for safekeeping.
