On the edge of the East River, there lived a foreign tribe with scales on the backs of their ears, living in the water. The beads of weeping turn into tears, which are priceless; the anointing that burns the lamp will last for thousands of years. The silkworm silk is like a feather, and its scales can cure all kinds of diseases. After death, they turn into clouds and rain, rising to the sky and falling to the sea.
