Under the guidance of the teacher, Liu has made great progress in traditional Chinese medicine, and soon became familiar with the relationship between patients' symptoms and corresponding pulse conditions, but it is far from enough to understand theoretical knowledge without practice.

In order to enable students to understand the changes of pulse condition, Yang Zhixun has come up with many methods, one of which is to touch the guitar strings. Liu studied very hard in this field, and even broke his grandmother's guitar string, which shows his hard work.

Later, Liu became more enthusiastic about practice. In pulse diagnosis, he combines the patient's pulse condition with symptoms, draws conclusions according to symptoms and pulse conditions, and then makes further diagnosis and treatment.

After studying and practicing day after day, Liu's medical skills are becoming more and more exquisite, and his logical thinking is very clear when he sees a doctor. He can explain the disease well for patients and tell it in a way that is easier for everyone to understand. Even people who don't understand medicine can be very clear after listening to Liu's explanation
