King Xuan of Zhou ruled China 800 years before Christ. He wasn’t a nice guy. He heard a rumor of a dangerous woman in the town of Jiangshan so he ordered all the women there killed. Du Bo, the Duke of Tangdu, objected so Xuan ordered him killed too.
The Duke, though, said he was coming back. Three years later Xuan had a dream where Du Bo shot him with an arrow. He fell ill and died.
