Similarly, "at least one of a, B, C, and D" means that there may be fifteen relationships, which may mean: fifteen cases of a alone, B alone, C alone, D alone, a and B in combination, a and C in combination, a and D in combination, C and B in combination, D and B in combination, C and D in combination, a, B and C in combination, a, B and D in combination, a, C and D in combination, B, C and D in combination, and a, B, C and D in combination exist.

In the present application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" means two or more unless explicitly defined otherwise.

The above description is only an optional embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
