What are the characteristics of American style? What's the difference between European style and European style?

compared with the European style of "wearing gold and silver, complicated lines and attaching importance to carving", the American style is simple, clear lines and appropriately decorated. It clearly expresses the nostalgia of Americans for history, and at the same time, it has the characteristics of making European royal furniture popular. While retaining the European classical style, it also pays attention to adapting to the modern living space, forming its own styles and characteristics.
