I’ve just finished learning ‘Mastering Chinese, Listening & Speaking 6’ (会通汉语 – 听说6). It’s an OK language-learning book, on the upside there aren’t as many idioms as the Developing Chinese series (发展汉语). The first chapters are extremely difficult, the last few are just pure propaganda: An American lady who lives in Beijing complimenting how well the government has done (“A miracle!”), and praise for the One Belt One Road initiative & the Confucius Institute.
Please, I’m trying to learn a language. Keep it interesting!
