Whalestone:

The stone is 9.2 meters long and 4.2 meters in circumference. Its head and tail are smooth and bright, as if just emerging from the water. Why is this happening? Because the whale fairy to help the bamboo temple abbot to surrender the Black Dragon after fear of the Black Dragon again, they settled here, every day in this direction to monitor the Black Dragon, over time to turn the fairy to stone. There is also a true story about this stone. It is said that a villager saw that the stone was quite smooth and wanted to chisel one into his home as a stone mill. However, after three strokes of the Chisel, the clear sky was suddenly overcast with dark clouds and thunder. The stonecutter was so frightened that he started to run away, and then he got sick. It shows that this stone is spiritual, as the saying goes: touch the head of a whale, a lifetime to eat and drink without worry; touch the back of a whale, a lifetime of glory and riches and honor.
