design concept

​

In order to make my tri-fold more distinctive, I cut off a small corner, which means that the digital class will not be framed by the original form, and I put a logo under the cut corner. It is a picture made by the English abbreviation DLEC of the digital class. This picture is symmetrical from top to bottom and left and right. In the middle, I use a light bulb to connect the four major courses of the digital class, and the light bulb is like no matter what you have. Aura, try to make it come true and bright, don't just try to make it dark in your mind.
