So i saw this one and loved the whimsy. It reminds me a little of a drawing by Breugel. Anyway, i was curious so i researched the story behind this one.
The story seems to go that Kinko (Qin Gao) was a Daoist sage (Sennin) who spent the first 200 years of his life painting fish. He had such respect for them that he would never harm or eat them. The Dragon lord of the river kingdom sent a giant fish to invite him to come and be his guest, so Kinko told his students he would return and rode the fish under the water into the river kingdom. He was a guest there for around a month and, upon returning meets the god(dess) Kannon, who gives him a scroll that teaches the Buddhist way of protecting all life.
Anyone have any examples from this legend? I've only seen this one and it (and my wallet) is decidedly low-end.
