Is there a relationship between picking Wei in the Book of Songs and picking Wei in the painting?

A species of the genus Vicia in Leguminosae, whose scientific name is "Save Vicia", is called "Dawocai", and its seeds, stems and leaves are edible. Picking EU describes the scene of picking EU. The picture of picking Wei shows the scene of Boyi and Shu Qi doing Wei in shouyangshan. Eating is also a "taste", which is recorded in history books. It doesn't matter whether these two kinds of "prestige" are one thing or not. It is important to understand what this poem and this painting represent.
