Spanish has a lot of retroflex. If you can't explain clearly, you will be laughed at. I've been there myself. Seeing how hard you work, it will be easier to be young. It took me about 2 years to learn the basic pronunciation standards, while it took my mother 6 years. In addition, other pronunciations are very simple, and most of them are the same as those of Chinese Pinyin. Personally, I think pronunciation is simpler than English, because there is only one pronunciation, so I can write and read at the same time.

I hope it will help you, and hope to adopt it. Source:/kloc-immigrated to Spain in 0/2 years.
