In the 14th-century historical novel, Romance of the Three Kingdoms (三國演義), the generals in the Dongwu (东吴) kingdom conspired to murder Liu Bei (刘备), head of the Shu Han (蜀汉) kingdom, by inviting him to their territory with the promise of their king Sun Quan (孙权)’s sister for his wife (甘露寺招亲). When Liu Bei was trapped in Sun Quan’s camp, he seized an opportunity while he was standing beside a large rock in the garden. Taking an attendant’s sword, Liu Bei pledged to Heaven, ‘If I am destined to succeed in my mission of reviving the Han, let this sword cut through the stone. Otherwise, let the stone remain intact.’ As he struck, the stone split in two. When Sun Quan came onto the scene and asked Liu Bei what he had wished for, Liu told him a lie to throw him off the scent.

Sun then gripped his own sword and cried, ‘I, too, shall put a question to Heaven.’ To himself, Sun Quan swore, ‘If Dongwu is to thrive, let the rock split!’ The giant stone broke again with Sun’s strike!

This tale aptly illustrates the expression, ‘being strange bedfellows’, i.e., sharing the same bed, but having different thoughts and dreams. The cross cracks on the rock are evidence of two strange bedfellows’ inner thoughts.
