Literally, the phrase "the green mouth of the universe" next to "Yiwu of the world" seems to have no clear connection. But from the commercial and geographical point of view, Yiwu is a county-level city in Zhejiang Province, China, which is famous for its small commodity market, while Qingkou is a town in Jiangsu Province, which is also famous for its small commodity market. Therefore, "Yiwu of the world" and "Qingkou of the universe" can be understood as "small commodity market of the world" and "small commodity market of the universe". Yiwu and Qingkou are both famous for their small commodity markets, which are well-known all over the world.
