The first volume (4 volumes in total) of A Comprehensive Course in German is published by Shanghai Foreign Language Education Press and edited by Chen.

This is a relatively new textbook for the German Department of Shanghai International Studies University. This is a CD with written records. Although it is a textbook for the German Department of the University, middle school students can fully understand it. After learning the first book, they can continue to learn the second, third and fourth books.

It is very important to lay a good foundation when you start learning German. German professional textbooks are much more practiced than public German textbooks.

Another thing is to buy a good German-Chinese dictionary and consult it frequently. It is recommended to buy the Shi Lang German-Chinese Dictionary of FLTRP. The New German-Chinese Dictionary of Shanghai Translation Publishing House is also acceptable, with a large vocabulary and many words used by science and engineering majors. After studying 1-2 years, I bought a German-German dictionary in Amazon, Germany, and recommended a Duden comprehensive dictionary and a Warwick German dictionary. Seriously, learning a foreign language, if you use the original dictionary, can only be considered a beginner.

Also, don't fall behind in English study. English is more important than German. I wish you success in your study. * * * Encourage!
