When I was a graduate student at Fudan University, I read Zeng's The First Volume of Quantum Mechanics and the one you mentioned, but it was too difficult to read mainly Zeng's and Zeng's, especially the Selected and Analytical Exercises of Quantum Mechanics edited by Zeng. This is not a normal abnormal condition. The majors of optics and physics in famous universities such as Peking University and Fudan University recommended quantum mechanics as the textbook of the first volume of quantum mechanics ... However, there were actually three textbooks about quantum mechanics. One is called quantum mechanics, which is divided into two volumes, one volume and two volumes. One is a course of quantum mechanics, and the other is an introduction to quantum mechanics. I suggest you read the first volume and an introduction to quantum mechanics at the same time. That's what I did. Because the two books are very similar in content, and many chapters are even identical, the difference is that quantum mechanics is deeper than the introduction in many places, and the theoretical model adopted is more universal than the wheel, which adds a lot of content. So compare these two books together and read them at the same time. If it is difficult to understand, it is better to read the introduction first and then thoroughly understand it through the original quantum mechanics, which is very efficient. At the same time, you can also find this problem set to assist your study. I used Quantum Mechanics-Tutorial Textbook for Postgraduate Entrance Examination by Tsinghua University Publishing House, edited by Shi Shouhua, with a green cover. But in fact, most of the above questions are actually Zeng Jinyan's after-school exercises of quantum mechanics, with answers, processes and even explanations, which are basically equivalent to synchronous exercises and are very easy to use.
