WHy does 日本动漫 always have to 显示 the character's mouth when he/she is talking?

i never thought of that till now?! XD

Their making it like an actual tv drama 或者 thriller movie. It's normal to do a close up of the character if something important comes up 或者 leads to a exciting scene. Although i'm not a 粉丝 of 唱歌 and 展示 the face cause it doesn't come out well.

Are u an elementry student 或者 something to ask me stupid questions??????????????????????????????????????????????????????????????????????????????????????????????????????????????Actually i never thought of that.
