In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

It should be understood that, although the steps in the flowcharts of the figures are shown in sequence as indicated by the arrows, the order in which the steps are performed is not limited to the sequence indicated by the arrows. In some implementations of embodiments of the present application, the steps in the various flows may be performed in other sequences as desired, unless explicitly stated otherwise herein. Moreover, some or all of the steps in each flowchart may include multiple sub-steps or multiple stages, depending on the actual implementation scenario. Some or all of the sub-steps or phases may be executed at the same time, or may be executed at different times in a scenario where the execution time is different, and the execution order of the sub-steps or phases may be flexibly configured according to requirements, which is not limited in the embodiment of the present application.

The foregoing is only a part of the embodiments of the present application, and it should be noted that it is within the scope of the embodiments of the present application that other similar implementation means based on the technical idea of the present application can be adopted by those skilled in the art without departing from the technical idea of the present application.
