I got it purely out of interest in the Chinese language, which I have been studying on my own sporadically. Having browsed through and read various chapters, I can say that it is really well-written, easy to understand (even for Greeks) and unique in its kind, as Chinese grammars, especially in Greek, are almost nonexistent. If you are learning Chinese, I believe it is necessary. However, be careful, as it says in the title, it is a grammar book and not a book for learning from scratch, so it should be combined with some other source.

An essential reference work for Chinese grammar – comprehensive, well-documented, and extremely useful
This is a book that covers the entirety of Chinese grammar, from the basics to the most complex phenomena — a true tool for students of every level. It analyzes with clarity and depth even structures that are often ignored or not adequately explained, even by native speakers. Indicatively, the famous "是...的" as well as the complex phenomenon of "了" are presented in an understandable and fully enlightening way.
The way the author — obviously with many years of experience and excellent knowledge of the language — conveys her teaching in written form is impressive. This is not simply a grammar manual; it is a comprehensive guide that offers unique content: specialized vocabulary, useful expressions, and information that one does not easily find in other books of the kind.
Having studied various sources, both Greek and foreign, I can say with certainty that this book is — without exaggeration — one of the most complete of its kind. In contrast to other, otherwise popular, editions that proved disappointing, this work stands out for its quality, structure, and practical value.
I highly recommend it to anyone who wants to seriously deepen their understanding of Chinese grammar. It is a resource that can stand the test of time for many years!
