"Examination guidance and full-reality simulation test" is what we commonly call light one, while "classic problem solving and passing the test" is what we commonly call light two. As the name implies, the guidance of light one is mainly based on the exam-oriented guidance of knowledge points in each chapter.

Looking at the light guide book, the first thing that comes to mind is the QR code in front of the knowledge point. In the 20 14 Easy Love Guide, there is a two-dimensional code the size of a fingernail before the title of each chapter. This small pattern is related to the wonderful course explanation of the famous teachers in Dongao, which is also a unique feature of Qingyi. Where can't you just watch the video to explain this knowledge point and gently sweep it?
