You should be able to learn! The professor in the history department of our school has studied it, and now he practices in the playground every morning. In the past, he was in poor health and often took vacations and was hospitalized. Now he is much better, and even seldom catches a cold! When he took elective courses this year, he always boasted about how well he practiced the ancient Book of Changes. We all joked that he was the spokesman of Jin Jiazhou, haha.
