Shi Tianzhang's voice is very special, soft and clear, with a sense of luxury in elegance and a wide range. It can be described as "neutral" for his soft and charming voice like a floating cloud. Its high-pitched sound quality can almost pretend to be a female voice. Therefore, some ambiguous neutral roles belong to him. Judging from its performance, his sound quality is very good, and the high and low voices are very metallic. Therefore, most of the roles played are gentle, honest and full of neutral beauty. For example, in "EVA", "Kaworu Nagisa", whose appearance time is very short, but whose personality is very high, has a little ambiguity and obscurity in the clean and innocent tone, which is very suitable for the role with unique temperament. The "Eight Rings" in travel notes, with its intellectual voice rich in metallic texture, combines the gentle and amiable appearance with the agile and meticulous, lonely and painful inner world, and perfectly interprets this contradictory figure, thus gaining the support of a large number of fans. Shi Tianzhang can not only play neutral roles like Zhu Xun and Pig Bajie, but also play "I love Luo" in Naruto. In The Silver Soul, Katsura Kotarou, a complex character with delicate appearance and plain essence, is also interpreted to the extreme. With his efforts, he has created many impressive and popular characters, and has an irreplaceable first-line seiyuu position in seiyuu, which also adds a unique color to Japanese comics.
