1936至1937年间，围绕李健吾与卞之琳关于后者之诗集——《鱼目集》的系列论争，即文学史上的“圆宝盒”事件。这一事件，虽然不曾引发激烈的论争，但是却在关注过此事件的人们心中留下了长久而深远的影响、并与其时文坛的反思倾向具有某种意味深长的契合。本文从《圆宝盒》一诗的文本出发，通过细读揭示此一事件的广泛文学史影响、批评与诗的深层关联；并着力探讨1930年代后整个中国诗坛对早期诗论话语规则、以及语体诗表现能力的反思与新的建构，以期在现有条件下对白话诗的发展有所思考。

Bian Zhilin’s poetry anthology Yumu Ji touched off a heated controversy between the writer and Li Jianwu in around 1936, which is called the Jewel Case Event in the history of Chinese literature. Based on the poetry Jewel Case and the event’s broad influence, the essay tries to reveal the different values of poetry and criticism by the text’s deep reading, and discuss about the retrospection and construction on early poetics rules as well as the performance of colloquial poetry in the Chinese Parnassus after 1930.
