In 1651 he fled to the island of Kinmen, which in 1663 was taken over by the invading force. His grave was discovered on the island in 1959, which disproved the theory advanced by the 18th-century History of Ming that he was killed by Koxinga. His eldest son, Zhu Honghuan (朱弘桓), married the fourth daughter of Koxinga and went to live in the Kingdom of Tungning Taiwan under the protection of Zheng Jing, his brother-in-law and worked as a farmer. Another Ming Prince who accompanied Koxinga to Taiwan was the Prince of Ningjing Zhu Shugui.
