I like Turkish very much. Although I am not proficient, I am an old self-learner. It was these books that I bought that year: Turkish textbooks of FLTRP. I remember a * * *, there should be six books, but I bought it in 2009, and I can only find the first two books on the market, including the most basic grammar knowledge. Turkish spoken language is also from FLTRP. Turkish Chinese Dictionary of Commercial Press. Very expensive, but very detailed. The disadvantage is that these books don't include audio materials, at least I didn't find them at that time. So I can only try my best to collect audio on some minority forums. Now there are more videos and audio in Turkish teaching than before, so we must make good use of them, because pronunciation is the foundation.
