Once upon a time, there was a river fish that couldn't find the water source. After flopping for a long time, the endless ocean appeared in front of him. The river fish's eyes were filled with the sparkling waves of the sea and the breath of sunshine. Ignorant, it jumped, but the ocean was not the home of river fish. The river fish climbed back to the shore with difficulty and encountered a shallow pond with a warm atmosphere. He jumped in again without hesitation.
Purpose: Rare and endangered fish, protecting water sources
