Couplet: I come a thousand miles, Wangjiang, Plum Blossom, Straight.

There is a couplet on the Yellow Crane Tower:

I came thousands of miles to see plum blossoms on the river until the red sheep was robbed;

Who left forever? Hearing the jade emperor in the building, he called back the yellow crane to fly high.

Excuse me, what does the red sheep here mean after robbery? Where did it come from? Is there any textual research? Be specific.

Red sheep robbery refers to catastrophe and social turning point.

In the Southern Song Dynasty, Chai Wang, a fortune-teller, drew the attention of the imperial court with the book Bing Ding Gui Jian: every afternoon in Bing Ding, there would be a national disaster. The heavenly stems "C", "D" and the earthly branches "Wu" belong to fire in the five elements of yin and yang, which is red, while "Wei". Later it was called "Red Sheep Robbery". The most painful memory of Song people is "the shame of Jingkang", which happened in Bingwu year (1 126). According to its statistics, it took * * * years from Bingwu, the 52nd year of Zhao Xiang, King of Qin, to Ding Wei, the 12th year of Tianfu in the Five Dynasties (AD 947).
