Ladder Verse

Come down

Yesterday, even today

Hanging in the laurel forest

Golden ladder

Emerald ladder

Come down and wait--

Show birds with red lips

Melancholic budgerigar

Old faint parrot

The moon slept in the clouds

Clear skies

Yellow flowers of laurel are drifting

Climbing on the emerald ladder

Come down and lean on there--

color

bright

Leave a faint distant sound

Fantasy beasts

Where do you want to go?

waiting

Below the moon

The dark petals of laurel

Footsteps of the annihilated girl

How peaceful is day

Yesterday, even today

Fantasy beasts

Shiny mottled

Climb up and down the golden ladder

Appreciation of Ladder Poetry

This poem is included in the first collection of poems of Saijo 80, the "Golden Collection", which is widely regarded as "the most beautiful collection of symbolic lyric poems in the Taisho era. This love poem mainly expresses the eager expectation and loneliness of young men waiting for their lovers to fall in love. The poet places the scene of love in the laurel forest in autumn. Autumn itself means harvest, and it symbolizes the emotional season of youth waiting for the fruits of love. The golden osmanthus not only has bright colors visually, it reflects the lightness and excitement of young people waiting for lovers, but also silently makes readers feel the influence of flowers, adding a warm and romantic atmosphere.

The whole poem is divided into five sections. The "ladder" is the object that the first half focuses on, and it is also an important tool and way to understand the poem. The "hanging in the laurel woods" ladder is a symbol of the path to the lover's soul. The young man repeatedly shouting "Come down" to his favorite person is an urgent call to open his heart to his lover.

The performance center of the second half shifted to the "small beast". The "little beast" in "Guo Lin Shu" is full of vitality, sometimes brave, sometimes cowardly; sometimes determined, sometimes cowardly. The "little beast" is actually the materialized form of love and lust in the youth. It wanders and runs around the "ladder" that symbolizes the road to lovers, and the ultimate purpose of these activities is to wait for love. The materialized "little beast" vividly shows the complex psychology of emotional agitation and rational calm when young people are exposed to the rapids of love.

The biggest feature of the whole poem in artistic performance is the beautiful color and the artistic conception built on it. This is an important expression of the poet's inheritance of French symbolism. The natural color of autumn is bright yellow. "The setting of the osmanthus tree, J. Sui is intended to take the color of osmanthus, and the main performance object" ladder "is also described as" gold "and" agate ". Color and autumn and flower color achieve a high degree of harmony and unity, which together symbolizes the virtue and eternity of love, truth and faith, and enhances the visual appeal. However, the color of the whole poem is not single. In the basic color, the dripping red of the bird's beak And the whiteness of peacock feathers, these bright colors interspersed between them, which greatly stimulated the reader's visual nerves, so that readers can better grasp the emotional pulse of the youth, so as to reach a state of resonance. In addition, the description of the scene is full of warmth The quietness and beauty of Tianmei, at this time, the silence is better than the sound. The traditional Eastern writing method uses static writing to maximize the contrast of the turbulence and loneliness of the "little beast".

The poetic features of the poem are also more prominent. Saijo 80 is a famous ballad and wrote in his book "Modern Nursery Rhyme Speech": "The nursery rhymes should first be" poems ", and it is when the artist observes life intuitively. The content that I was really touched was written in poems that are easy for children to understand. Although "Ladder" is different from folk songs such as "Straw Hat Song", the language is also influenced by the light and natural style of folk songs. The form of poetry is free and flexible, and the length of the syllable syllables is unlimited. It expresses the poet Sui feeling freely.
