Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that some display panels in the prior art are directly fixed on the wall. This display panel cannot be moved and used in a single way, and its position cannot be adjusted. Supported by brackets, this kind of display panel cannot quickly adjust its height during use, is not convenient to use, and has no expansion function. When the teaching content is large, it cannot meet the shortcomings of the use requirements. A kind of teaching and display device for teaching Chinese as a foreign language is proposed
