In terms of price, I think Peiwen foreign language is more reasonable. There are five of them in a small class, and they train one by one. There is a kind of literacy in Chinese. They are not composed of independent words, but of radicals. For example, the word "Chu" has the word "Dao" on the right and the word "Qiu" on the left, so it cannot be written independently. It comes from the word "clothes". Therefore, the original meaning of "going out" is "cutting clothes with a knife" and "the beginning of cutting clothes". For beginners, it is easy to understand and remember such "cognitive words" as long as they know the source and meaning of radicals through guidance. Interestingly, there is also a word formation similar to "knowing words" in French. It is not a new word synthesized by two independent words, but a new word synthesized by an independent word and a word-forming component that cannot exist independently. You will benefit from going there for life.
