The reason why Jia Zhangke takes the cake in the rising generation of the directors is close to his insistence in realism aesthetics. He always sticks to his own realism aesthetics by using the calm full-length shot to record the true life of the little ones. He silently sticks to his principles in the current trend that all commercial block-busters swarm, without advertising and press publicity. What he does is to express his feeling towards the society. Because of this, he becomes a great person in the Chinese Film Festival from an unimportant person. Jia Zhangke once said, " I do prefer the realism aesthetics. That is not to say our era only can be expressed in the form of the realism, or to say that our inner world can be expressed by realism. The realism ways, I always think, is the most proper for the film reality, through which the true beauty of the film can be got. The so-called beauty of the film is the beauty expressed by the film reality. Just like the process when you do painting, you should study the target; the most significant feature in the film is its realism." Bazin and Kracauer said so dozens of years ago. Specific to every director, they all need a selective process. To me, " I choose the ways of realism." The greatest characteristics in Jia Zhangke's films are its realism aesthetics.
So far, the Hometown Trilogy is his most successful works, for the film gives a description on his hometown and his real experiences, although it is shot in his early filming period and is immature. Therefore, the Hometown Trilogy expresses the director's faithful feelings. The composing three films in Hometown Trilogy are full of realism aesthetics of Jia's style. As the two key words in the paper, Hometown Trilogy associate with each other technically. This paper sets examples of shooting languages to show the realism aesthetics from four aspects-the space, the figures, the sound and the shooting techniques in Hometown Trilogy. The paper is on an attempt to combine theory with practice.
