What does the nail mean in ancient poetry?

What does the nail mean in ancient poetry? In poetry, nail usually refers to fasteners or nails used to fix objects. In ancient times, people usually used nails to connect wood or fix the infrastructure of buildings. Therefore, in poetry, nails are often used to imply the close relationship between certain objects, or something inconspicuous but indispensable.

Nails in some ancient poems also have symbolic meanings. For example, in "it is hard to go", "The cost of pure wine is a gold cup, 10,000 copper coins and a hip flask, and 10,000 yuan for shame." In this poem, the word "ten thousand yuan" means "great wealth and great wealth", while "jade plate is expensive and shameful" implies that the poet can not accept money, precious food and drinks as an important part of his life.

In addition to metaphor and symbolism, nails in ancient poetry can also reflect an emotion. For example, Liu Yuxi, a poet in the Tang Dynasty, wrote in My Humble Room Inscription: "Wild geese fly by, and children's hearts beat. Jin Chai has a pair of hairpin, and the iron lock has Shuang Ye. " The "iron lock" here means "locking the heart", which expresses the poet's extreme dissatisfaction with the poor condition of the humble room. At the same time, natural and artificial objects such as "iron lock" and "golden hairpin" symbolize the poet's long and lonely feelings.
