What does the stage mean?

"Mirror table" is an ancient dressing table, which refers to a flat mirror that can reflect one's own image. There are shelves for putting cosmetics and tools under it, which is convenient for people to make up. This platform was popular in the Tang Dynasty and was usually made of gorgeous wood carvings or iron. In the early days, it was relatively simple, and most of them had only one convex mirror. Later, it gradually developed into the design of a rotatable polygon mirror. Nowadays, although there are many new dressing tables in modern fashion, the classical dressing tables still have certain charm.

Besides dressing table, there is another explanation, also called dressing table, which refers to the mirror assembly used in the camera. This "stage" has two main functions. First, it can reflect light to the viewfinder and the focal plane of the camera, helping the photographer to adjust parameters such as focal length and exposure; Secondly, this kind of mirror can form reflection inside the lens mirror through its unique structure, so that the camera functions such as autofocus and anti-shake can operate normally.

"Mirror Stage" can also be used in metaphor to express a way of thinking that reflects one's own shortcomings. This mode of thinking usually means that people reflect on their words and deeds and find out the problems and misunderstandings. This kind of "introspection" can make you get all-round and multi-angle understanding and improvement, so that you can make better progress and growth. Through the thinking mode of "mirror platform", people can show themselves a true and objective self and avoid affecting their progress because of personal self-limitation.
