During the Xianlong era, there had been frequent outbreaks of plague and the local officers could not solve the problem. At that time, the patrol officer Shen Jia-Rui had heard much about the Su royal highness and his blessings. Thus, he went to him to pray for care of the people. Soon the epidemic outbreak was gone and the news of the god's blessings spread all over Taiwan and the coastal area in China. Anyone who prayed had been answered. From Quanzhou, Shishi, Jinjiang and Qianjiang, there had been prays that were answered. Every several years, the god instructed to go back to Lukang and worship the ancestors. Many temples and gods were originally from China. However, the Su royal highness in Fengtian Temple began right in Lukang, which was rare to spread from Taiwan to China.
