This is the origin of many imaginary animals that serve in the role of guardian deities. This point reminds me of a recent news report on television that said a hippo in the Kaohsiung zoo had been injured by malicious visitors who had thrown more than a hundred stones at it, some of them over 10 1bs. in weight.
談到這裡，我想到前些時候，高雄壽山動物園裡的河馬，慘遭惡客修理受傷，園方從池中撈出丟擲河馬的石塊達百餘之多，其中有的重達十來公斤。
