宋代是一个商业空前繁荣、世俗文化勃兴的时代，诗歌作为一种雅文体，其所书写的世俗日常商业活动不仅得到了审美化的诗意呈现，也沾染上了鲜明的宋代文人趣味。

首先，随着商业的发展，宋人淡化了古已有之的厌商情绪，抛却了一些固有的偏见，能够更多地从审美的视角看待作为商业活动的买卖行为。宋代诗人可以借助审美性物品，比如花卉自身的美感，赋予买卖以雅致的诗意。这种诗意的产生一方面来源于审美性物品本身在视觉上的观赏价值和文人雅事给人带来的美的感受，另一方面也是因为作为媒介的叫卖声可以打破时空的局限给诗人带来巨大的审美体验空间。此外，一些本与商业无关的自然美景在宋诗中也成为了可以买卖的审美性物品，这在宋前是比较鲜见的。

其次，在审美性物品的买卖之外，生活中更常见的是日常生活用品的买卖。宋人基于对生活的细腻体验，在诗歌这种雅文体中对日常生活中的俗物买卖进行了审美化的呈现，使其在宋代诗人的书写中产生了诗意，这主要有三条途径：第一，宋代诗人主动地从古典文献里汲取到文学传统中的养分，比如从卖饧与吹箫来看，诗人关注到了买卖俗事与庙堂雅事的关联，并将这种关联固定下来，也将其中蕴含的雅意发扬了出来。第二，基于日常生活实况，宋代诗人也常常会将买卖活动与具有丰富文学内涵的典型意象关联起来一并书写，于是便赋予了世俗商业行为以这一典型意象的文学内涵，比如鱼的买卖与酒意象的关系就是如此。第三，在物质基础相对雄厚的条件下，宋代诗人自身观念上的超越使他们可以开始用娱乐和审美的眼光看待世俗商业活动，也逐渐能够以扬弃悲哀、自得其乐的精神应对现实经济限制，比如宋代诗人笔下鱼的买卖活动就反映了这一点。

最后，买卖这种世俗商业行为进入到宋诗的书写中，不仅被诗人赋予了雅致的诗意，还沾染上了文人的生活趣味和价值取向。宋代重视文化教育，随着雕版印刷技术的广泛应用，文化生产空前兴盛。在此影响下，一方面，宋代文人热情地购买诗文书籍，他们不仅花费重金买书、藏书，还劝勉后生勤奋读书。另一方面，在经济上陷入困境或仕途上遭遇坎坷时，宋代文人也对售卖诗文书籍用以换钱的行为抱有宽容的态度。

Song Dynasty is an era of unprecedented prosperity of Commerce and flourishing of secular culture. Poetry, as an elegant style, not only presents the daily commercial activities aesthetically, but also has a distinct taste of literati in Song Dynasty.

First of all, with the development of Commerce, people in Song Dynasty played down the ancient business aversion and gave up some inherent prejudices, so they could see the business activities from the aesthetic perspective. The poets of Song Dynasty can give elegant poetic flavor to business with the help of aesthetic objects, such as the beauty of flowers themselves. On the one hand, this kind of poetry comes from the visual value of aesthetic objects and the aesthetic feeling brought by literati's elegant things. On the other hand, it is also because the peddling sound as a medium can break the limitation of time and space and bring a huge aesthetic experience space to poets. In addition, some natural beauty which had nothing to do with commerce also became aesthetic goods that could be traded in Song poetry, which was rare before Song Dynasty.

Secondly, in addition to the sale of aesthetic goods, the sale of daily necessities is more common in life. Based on the delicate experience of life, people in Song Dynasty aesthetically presented the vulgar trade in daily life in the elegant style of poetry, which made it poetic in the writing of poets in Song Dynasty. There are three ways: First, the poets of the Song Dynasty took the initiative to draw nutrients from the classical literature. For example, from the perspective of selling bamboo and playing flute, the poets paid attention to the relationship between the common business and the elegant affairs of the temple, fixed the relationship, and carried forward the elegance contained in it. Secondly, based on the daily life, the poets of Song Dynasty often associate the business activities with the typical image with rich literary connotation, so they give the literary connotation of this typical image to the secular business activities, such as the relationship between the business of fish and the image of wine. Thirdly, under the condition of relatively strong material foundation, the poets of Song Dynasty began to treat secular commercial activities from the perspective of entertainment and aesthetics due to their transcendence of their own ideas, and they were gradually able to deal with the realistic economic restrictions with the spirit of abandoning sadness and enjoying themselves. For example, the fish trading activities described by the poets of Song Dynasty reflected this.

Finally, the common commercial behavior of buying and selling entered the writing of Song poetry, which was not only endowed with elegant poetic flavor by poets, but also contaminated with the life interest and value orientation of literati. The Song Dynasty attached great importance to cultural education. With the wide application of engraving printing technology, cultural production flourished unprecedentedly. Under this influence, on the one hand, the literati in Song Dynasty enthusiastically bought books. They not only spent a lot of money to buy and collect books, but also encouraged posterity to study hard. On the other hand, when they were in economic difficulties or suffered from ups and downs in their official career, the literati of Song Dynasty also had a tolerant attitude towards selling books in exchange for money.
