COMPAREED WITH THE POETIC EXPERIENCES AND PHENOMENA WHASE NATURE HAS BEEN DETERMINED DURING THE LITERARY HISTORY, THE'THIRD GENERATION'POEMS, NOW STILL AFTER THE AGITATION, AND TRYING FOR CERTAIN FIRM TRANSFERENCE, ARE RATHER LIMITED IN DEALING WITH HISTORY AND THEORETICAL SIGNIFICANCE, WHETHER ON TIME SPAN OR SPIRITUAL LEVELS. THIS PAPER, THEREFORE, LAYS EMPHASIS ON DESCRIPTION AND INTERPRETATION AS WELL AS PRUDENT VALUE JUDGEMENT, INSTEND OF ARBITRARY DECISION.
