Physical characteristics: Zhang Wuji's physical characteristics were vague in the book and there was no particularly obvious description. However, the image of Zhang Wuji on TV was more specific. For example, he had black hair, a tall and strong figure, a delicate face, a high nose, and so on. 2. Character traits: In the book, Zhang Wuji's character is gentle, kind, and righteous, but he also has some shortcomings such as indecisiveness and lack of decisiveness. On TV, Zhang Wuji's character was more mature, steady, and responsible. At the same time, it was more complicated because he had experienced many setbacks and tests in life. 3. Character setting: In the book, Zhang Wuji is a young teenager. He doesn't have much life experience, so the character setting is relatively simple. He is a good person with a strong sense of justice. In the TV, Zhang Wuji's character setting was even richer. He had experienced many setbacks and tests in life and grew into a more mature and responsible leader. At the same time, he was more complicated and had his own ideas and pursuits. 4. Character image: In the book, Zhang Wuji's image is relatively full but there are also some vague places. The image of Zhang Wuji on TV was more specific, more three-dimensional, and more expressive.
