Introduction to the long couplet: The long couplet was written by Gao Wuxiong, a great calligrapher and Rui of the Nine Ranks. First couplet: History opens in the hot summer, literature spreads in Zhongzhou, poetry and painting are heroic in Wumensong County, and there are many wise men in the mist. Righteousness shakes the rivers and mountains, loyalty reaches the sun and the moon, five thousand years of wind and rain, and blood, all singing praises to the present and the past. Second line: The nine peaks are dyed green, the waves surround the clouds and dreams, the water shield perch regrets the Huating on the road, and the scenery can be judged by appreciation. The clothes and quilts are all over the world, and the grain is tribute to Kyoto. Six hundred miles away, the territory is limited, and there are two kinds of crowns, Chinese and Western. Chanting history and singing scenery, the perfect combination.
