A discussion arose from this post In ` 向谁说`, does `向` play the same role / have the same meaning as `对`?
What is the role of the noun after 向 in "向 + noun + verb"?
Is it the object? Someone argued 向 is a preposition, which introduces a prepositional phrase, therefore, the noun after 向 cannot be the object.
So, What is the role of 美國 in "中國向美國報復"?
