The Yin merchants have been scattered. Which of the following does not have a Yin merchant? Chu or Song~~~~~

The Song Dynasty was a feudal state of the descendants of the Yin and Shang Dynasties. King Wu of Zhou defeated Zhou and the Shang Dynasty perished. According to the etiquette of the enfeoffment system, even if the dynasty perished, the victor could not let the previous noble ancestors be extinct. Therefore, when King Wu enfeoffed the princes, he still enfeoffed King Zhou's son Wu Geng to Yin to honor his Song ancestor.

So your answer is Chu State.
