「唐詩現地研究法」是我十幾年來開發的研究方法，它的基本主張，乃是從真實與證據、寫實與求證的互動中，探訪唐人詩句的真相。 中國詩自古即有「古詩系統」及「樂府系統」之分，「寫實」乃是「古詩系統」詩篇的內在需求，作者需要寫自己之真實，來面對他的讀者，因而「指物寫實」的情況處處可見。這篇文章中，我提出六個「指物寫實」的唐詩實例，以實際的研究過程，說明「唐詩現地研究法」如何以唐人詩句為證據，進行「依詩求證」的研究。

The On-site study of Tang poems is a research approach I have developed for a decade. Its basic idea is to examine the truth written in Tang poetry by their interaction of facts and evidence. Since the times of ancient China, there has existed the dichotomy of the ancient poetic system (Gushi) and balladic (Yuefu) poetic system. Realism as a writing method is the internal demand of ancient poetry that emphasizes the author’s need to write about real things and actual feelings to their readers. Thus, realism, writing, and references to things in the human realm is a poetic phenomenon that can be seen everywhere in the Chinese poetic tradition. In this paper, I bring forward six Tang poems as examples of writing realism in reference to things and through a practical research process, I elaborate how on-site study of Tang poetry involves lines written by Tang poets as evidence to establish and confirm facts according to poems.
