There is a saying in Liu Baorui's cross talk that "the emperor's daughter-in-law is called an empress". What cross talk is it?

Mr Liu Baorui.

Poem: "There is a divination master who has strong skills and unusual clever calculations;" He figured out that there was an emperor before Beijing, and he figured out that the emperor's daughter-in-law must be called the queen; He counted the whole grains as big as this broad bean, and the underground crops he counted were growing sorghum; He counted his father's age in the aisle, and his daughter-in-law's mother must be a man's mother-in-law; Finally, this divination is more accurate, and the head is long on the neck.
