First, let's talk about the degree of portrayal in terms of appearance. For example, veteran actors Wang Renjun, Hou Jingjian, and Tang Guoqiang not only match the physical characteristics of the characters but also exhibit impeccable mannerisms.

Now, let's talk about our friend Liu Cheng Lin. Personally, I feel that his portrayal falls slightly short in terms of appearance. Perhaps the makeup or styling didn't fully capture the features of the historical figure. Let's also discuss his acting skills. Oh, I really don't want to be too harsh on an artist who is making an effort to express the emotions of a character. However, the fact remains: while other actors immerse the audience in the story with delicate and nuanced performances, Liu seems to be lingering outside the story.

He tends to be either overly exaggerated or appears wooden, making it difficult for the audience to immerse themselves. The use of vivid and imaginative figures of speech like "a single thought that can change the world" or "a single thought that can lead to downfall" is not merely for artistic embellishment. In fact, it's like adding seasoning to our everyday conversations—it adds interest and allows us to deeply contemplate the complex and subtle relationships between the character and the individual.

In conclusion, I must emphasize the utmost importance of careful and meticulous casting. After all, each historical figure carries profound significance and extensive influence, and any carelessness can easily tarnish the image of these great individuals.
