Abstract: A Lai's poem creation has not attracted adequate attention among the literary world nor the readers. However, it is an indivisible part and an important beginning of A Lai's literary creation. This paper is modeled on his collection of poetry So Mo River and mainly discusses the key subject of his poems. In his poems, A Lai writes about the Tibetan life and corresponding local culture, expressing his affection and quest for spiritual home. Thus, the Tibetan part becomes the most important theme in A Lai's poem creation.
