What language elements are difficult for foreigners to learn Chinese?

A while ago, I taught a little Turkish brother to learn Chinese, mainly speaking pronunciation correction, Chinese character writing and advanced reading. This little brother is my classmate, a rich second generation+official second generation, who is determined to become a sinologist and promote Sino-Turkish friendship. His native language is Turkish, and he is not allowed to send it to the support room in West, Fourth and Fourth from now on. The songs broadcast are voiced consonants, voiced consonants and voiced consonants, and Japanese songs are strange syllables spelled with big tongue vibrato and Chinese vowels. When I first taught him, he spoke Chinese without tone, and he spoke directly and quickly. Omitting many vowel syllables and complex consonant groups, he just reads only consonants (for example, my name is XXX, pronounced Wud, miz, jio, XXX). According to him, his Chinese teacher in Istanbul said the same thing. It's hard to speak Chinese. After the speech, he said that he would kill his Chinese teacher when he returned to China, but I tried my best to stop him. After he began to teach writing Chinese characters (Turkish teachers taught vocabulary and grammar in Latin letters), he felt that the image of Chinese in his mind had changed again. Recognizing Chinese characters has driven him crazy. The younger brother said, you China people are really awesome. You can live a normal life surrounded by such wonderful words every day. I began to teach myself Chinese characters before I taught him. Two years later, he can recognize no more than 1000. Many times he guesses newspapers and Chinese characters as his entertainment. However, after he began to try to write Chinese characters, he completely collapsed. He never imagined that the threshold for being a China person was so high. Come and tell me what's the difference between writing Chinese characters and drawing ... I smiled without saying a word, silently took out a comparison table of complex and simplified characters, a four-body calligraphy dictionary and a list of variant characters and put them in front of him. He simply said that my father wanted to return to China to inherit property. China is a cruel place.

Then I started advanced reading. However, Chinese characters cannot be read completely. So I don't know what I taught him after reading for half a semester. What impressed me most was that he once told me with a guess that he finally understood a scientific article and burst into a kind of "I have Chinese in my hand" with joy. I smiled again without saying a word and silently turned the textbook to the next page, Chen Taiqiu. At that time, he had not yet started to get in touch with ancient Chinese. After reading it for a while, my little brother looked up with a broken face and asked me, are these two articles really the same language? I said it was true. According to his roommate, he went back to the dormitory that day, looking dull, scratching his hair and throwing cups, which scared everyone. In this way, I finished teaching for a semester (my little brother is also very talented in language and has made rapid progress, and he has almost finished learning ancient Chinese at the junior high school level). After the exam, we both went out for dinner. After dinner, in a long nonsense, he patted his chest and sighed. Fortunately, there is not much difference between ancient Chinese and modern Chinese. At least the words are the same. Learn more about morphology and grammar. I smiled shamelessly for the third time and threw him a pamphlet about ancient and medieval sounds. The next morning, he sent me a text message saying that the Turkish people did not welcome me. If I dare to go to Turkey in the future, he will have me hacked to death. Finally, there is another funny thing. My brother's name is Bakar. However, this wonderful Turkish Chinese teacher named him Cabal in Chinese. Yes, it happened that the two syllables of his mother tongue name were spelled backwards, and then he told others that his Chinese name was this ... at first I didn't have the heart to tell him, but later I got familiar with it and spit it out after class. His expression is terrible.
