Maybe it was a gateway through which goods, ideas, and people passed. However, this is just speculation without further details about the particular 'China Gate' in question.
There are many possible interpretations of 'China Gate'. It could be a modern establishment as well. For example, if it's a restaurant named 'China Gate', the story might involve the owner's intention to showcase Chinese cuisine and culture. But again, more context is needed to accurately tell the real story.
I'm not entirely sure which specific 'China Gate' you are referring to. There could be various things named 'China Gate' in different contexts, such as a building, a location in a movie or a historical site. Without more specific information, it's difficult to tell the real story.
