From 1990s,China began to enter an era that value was split so as that the literary criticism has lost its own faithful character and independence gradually and been in subsidence confusedly.
自上个世纪90年代,中国开始进入一个价值分裂的时代,文学批评越来越失去了自己独立坚贞的品格,在迷茫中陷落:批评家丧失主体性,并导致批评标准的混乱;受大众传媒挤压,处境日益尴尬;越来越远离作品、远离生活,备受大众冷落。
