What is the concept of introduction? If you just learn the phonetic symbols, it will take a week at most, but the pronunciation rules of Korean will be consolidated at the intermediate level, so it is estimated that the primary school will be completed ~ if the primary school is good, it will take 160 hours, so it will take three months to arrive. If you want to learn pronunciation, I suggest you go to a training institution. Liz is fine. My classmates study there. You can choose to teach yourself after introducing phonetic symbols ~ because Korean is phonology, you can't understand any Korean characters!
