It is very insufficient for non-specialists to listen to. For example, when explaining a technique, you skip all the detailed explanations that are absolutely necessary for understanding the concept, such as whether it is a technique divided into steps and explained at once or whether each is a technique, and describe it vaguely. Also, there are cases where the sentence structure and order are the same as those of the Jeongcheogi exam preparation books on the market, so it sometimes makes you wonder if you are just reading that exam preparation book.
