According to historical records, Zhao Min proclaimed himself in Fuzhou at that time. However, Zhao Min's strength was weak, so he fled Fuzhou and fled to Nan 'ao Island. However, the Yuan Dynasty did not intend to let them go, so it sent troops to Nan 'ao Island. After learning the news, Zhao Min continued to flee with the remaining troops. However, many treasures that Zhao Min carries with him are destined to become them.
When they were hiding treasure, they planned to escape from Nan 'ao Island, but the Yuan Dynasty had already arrived near Nan 'ao Island, blocking Zhao Min's escape road and not giving them any chance to escape. Helpless Zhao Min had to throw himself into the sea, and the hiding place of their treasure became a mystery.
Although Zhao Min carved words on the stone wall near the treasure, it was difficult for others to decipher the meaning. So people haven't found the treasure yet, and it is still circulating among the people. If someone deciphers the meaning of the words on the stone wall, they can find the hidden place of the treasure. Many people also come for acne marks, but so far no one can tell the meaning of the 35 words on the stone wall, and the hidden location of the treasure has been passed down to this day, which is an unsolved mystery.
