What are the four plaques on the Yellow Crane Tower?

At the main entrance, there is a plaque with golden characters of "swallowing clouds and spitting dreams", and on both sides are couplets with the theme of Liu Haisu's "Dragon and Phoenix Dance": Deng Silou looks at heaven and earth in "Sijing Nujiang Map"; Introduction from the road, strange trees through the clouds, poetry out of sight. When I entered the main building, I saw a huge painting of the yellow crane. A couplet on the column in the hall reads the "famous" momentum of the Yellow Crane Tower: the river does not return, and the waves wash away the eternal sorrow; Refreshing from the west, clouds sweep the world.
