CH's core teaching material was written by Huibin (Helen) Zhu, the founder of the company, following the (HSK) Level Standards and Grammar Level Outline issued by the Chinese Ministry of Education. She also used these materials with her own students for many years.

The former cultural counselor of the Canadian Embassy, Claire Huot, who has studied Chinese and taught the language for some ten years at University of Montreal, has strongly commended the CH materials and method. As she said in her recommendation to publishers: ‘…I therefore know when I saw an excellent textbook for foreigners. Professor Zhu has written such a book. I know it works because my spouse has been studying with her since we arrived in Beijing, that is already nine months. From his notes, as well as his weekly newly learnt vocabulary, I can tell that her method is most efficacious…she has managed to show him gradually, in a ingenuous pedagogical way…, the dialogues she devised are extremely realistic, as well as down-to-earth, exactly what a student needs and appreciates'

Ms Zhu has been a popular Chinese teacher for 8 years, and has had many distinguished students, such as:
- Vice President of quality control of Volkswagen Group China
- Vice-President of the Beijing Hawaii Power Corporation
- General Manager for China of Valeo, the leading French car component manufacturer
- the wife of the former Norwegian ambassador to China

 And all the teachers at CH have been trained by experts and herself
