Introduction to the Gray Date Tree: Not long after entering the island, you will see a 500-year-old Gray Date Tree. This is a unique tree species on Jiming Island. The fruit on the tree is half the size of a wolfberry. Many red cloth strips are hung on the gray date trees, which are used by villagers to make wishes and pray for blessings. In the early years, there was a Dragon King Temple next to the tree, but it can no longer be seen due to its age.
