When Guan Yu defected to Cao Cao, Cao Cao gave him a gauze bag to store his beard. There is a saying that "the emperor ordered the temple to be built on his stomach." What does that mean?
When Guan Yu surrendered to Cao Cao, Cao Cao gave Guan Yu a gauze bag to hold Guan Yu's long beard to protect it from falling and being damaged. Later, when Guan Yu was named Hanshou Pavilion by Emperor Xian of Han Dynasty, he saw it and asked him to brush his beard on the spot. When Xian Di saw that Guan Gong's beard was so long, he said, "What a beautiful beard!" ! Since then, Guan Gong has also been called Beard.
