1. Analysis of 'Khi con tu hú' number 4
Question 1. Write a sentence starting with the words 'Khi con tu hú' to summarize the poem's content.
Why does the call of the cuckoo bird have such a powerful effect on the soul of the young revolutionary prisoner?
Answer:
- There are many ways to express this, but the sentence must meet two requirements:
+ Start with 'Khi con tu hú'.
+ Summarize the content of the poem 'Khi con tu hú'.
Students can write: 'When the cuckoo sings to announce summer, the prisoner envisions the vibrant and expansive summer outside, but feels suffocated and craves freedom in his cramped prison cell.'
- The cuckoo's call has a strong impact on the young revolutionary's soul because:
+ In 1939, Tố Hữu was young and passionate about life, newly awakened to the Party's ideals, actively involved in revolutionary activities with romantic joy. He was then captured and imprisoned in Thừa Phủ (Huế), a dark and isolated place. Being confined in a narrow, gloomy prison, far from the outside world, he felt intense pain and suffocation.
+ Isolated from the outside world, the poet listened attentively to every sound coming from outside the prison. At that time, his sense of hearing became the only way to feel connected to the freedom outside. Therefore, every sound was welcomed with eager anticipation: 'I listen to the sounds of life bustling outside / How joyful it is out there' (Tâm tư trong tù).
+ The cuckoo’s call echoes into the prison, signaling the arrival of summer. With a sensitive and perceptive soul, and especially with a deep thirst for freedom, the young revolutionary prisoner imagines a vibrant, lively summer outside, full of sounds (the cuckoo calling its flock, the cicadas, the kites in the sky) and bright colors (golden corn, rosy sun, blue sky). It is also a summer with a vast sky, where kites soar freely. All of this contrasts with the confinement the revolutionary soldier is enduring. Thus, the cuckoo’s call makes Tố Hữu envision a world of freedom full of life. This only deepens his feeling of the suffocating confinement within the prison.
Question 2. What do you think about the description of nature in summer in the first six lines of the poem? Which details lead you to this conclusion? Through this portrayal of summer, what do you think about the poet's emotions?
Answer:
The first six lines of the poem describe the summer landscape. It is a summer filled with life and energy. Details like the buzzing cicadas, the sweet fruit, the golden corn on the sunlit ground, the ripening rice in the field, and the kites soaring in the vast sky all contribute to this lively scene.
Through this portrayal of summer, we sense the poet’s deep love for life, his intense desire for freedom, and his sensitive, perceptive nature as a poet-soldier.
Question 3. The first and last verses of the poem both feature the cuckoo’s call, but the poet’s mood is different in each. Why is there this difference?
Answer:
The first and last verses both feature the cuckoo’s call, but the poet’s mood changes. Initially, there is excitement for the coming of summer, full of life (as mentioned earlier); but later, the mood shifts to frustration and sorrow (evident in the irregular rhythm: 6/2 in the eighth line; 3/3 in the ninth line), the use of strong words ('breaking down the cell', 'suffocating to death'), and exclamatory phrases ('Oh how unbearable it is').
The change in mood reflects the poet’s emotional journey. At first, hearing the cuckoo’s call, the revolutionary soldier naturally imagines a bright, free summer, reminiscent of the summers he once experienced. But later, as he becomes more aware of his prison confinement, the cuckoo’s call evokes a sense of deep frustration and sorrow. In reality, it is the same pain of the revolutionary prisoner—his yearning for freedom, detached from the outside world. The cuckoo’s call brings both a vision of the free world outside and a deep sense of suffocation within the prison.
Question 4. What do you think are the main artistic elements that convey the emotional impact of this poem?
Answer:
The emotional impact of this poem is due to several artistic elements, such as: the smooth use of the lục bát (six-eight) verse form; vivid and relatable imagery; delicate perception; sincere and intense emotion; and a natural shift in tone, which alternates between excitement, expansiveness, and sorrow, fitting the poet’s emotional state.

Question 1: Page 20, Literature 8 Textbook, Volume 2
How should we interpret the title of the poem? Write a sentence starting with 'When the cuckoo calls' that summarizes the content of the poem. Why does the cuckoo's call have such a profound effect on the poet's soul?
Answer:
Interpretation of the title:
The title refers to a temporal clause in a sentence – drawing attention.
The cuckoo’s call: a symbol of life and the arrival of summer.
When the cuckoo calls for its flock, it marks the beginning of summer, and in the oppressive, suffocating prison space, the revolutionary soldier listens to the vibrant summer outside, feeling an intense longing for life and freedom.
The cuckoo's call impacts the poet profoundly because it reminds him of the free, expansive summer, in stark contrast to his confined and oppressive prison life.
Question 2: Page 20, Literature 8 Textbook, Volume 2
Comment on the depiction of summer in the first six lines. Which details lead you to this interpretation?
Answer:
In the first six lines, summer is depicted with a cheerful, lively, and spirited tone.
The cuckoo’s call over the countryside, inviting its flock, sounds nostalgic and eager, signaling the arrival of summer.
Summer’s vibrant colors are reflected in:
The golden yellow of 'ripe rice', the red of 'fruits', the golden corn drying on the yard.
Moreover, the green of the expansive sky is also emphasized.
Additionally, the sounds of 'chirping cicadas' and the 'soaring kites' are quintessential summer details.
Thus, summer is portrayed as vibrant and full of life, presenting a beautiful and energetic season.
The poem makes the reader feel the vastness of the world in every direction – high, far, wide, deep. The poet senses summer through all his senses, showing both the sensitivity of an artist’s soul and the suffocating desire for freedom in a revolutionary soldier's heart.
Question 3: Page 20, Literature 8 Textbook, Volume 2
Analyze the mood of the revolutionary soldier depicted in the last four lines. Although both the beginning and the end of the poem feature the cuckoo’s call, the poet's mood in each is different. Why is this the case?
Answer:
In the last four lines, the mood of the revolutionary soldier is expressed with frustration, emphasized by the exclamation words like 'Oh summer!' and 'How can it be?', and verbs like 'want' and 'stamp'. These elements reveal the soldier's frustration and intense yearning for freedom and life.
The rhythm of 6/2 and 3/3, combined with strong verbs, creates a striking effect in these lines.
Although both the beginning and end feature the cuckoo’s call, the first six lines reflect a sense of joy, welcoming the arrival of summer. However, as the poet contemplates his imprisonment, he becomes aware of the suffocating reality of his confinement, and this realization turns his feelings into frustration and despair.

4. Artistic value

Line 1: The title of the poem acts as a supplementary clause in a complete sentence.

The title opens up the emotional flow of the poem.
The metaphorical and associative value of the cuckoo’s call is established right from the start. It represents the vibrant summer, the joy of life, the expansive sky, and freedom. Thus, the cuckoo’s call profoundly impacts the prisoner’s soul.
Line 2: The six Lục Bát verses skillfully unfold a world filled with life and vitality. Many typical images of summer appear in the poem: the sound of cicadas in the garden, ripe rice on the fields, the vast sky with flying kites, and sweet fruits.

The poem expresses the intense, delicate sensitivity of a youthful soul filled with love for life but yearning for freedom.
Line 3: This represents the prisoner’s pain, frustration, and suffocation, directly expressed by the poet. The verse’s irregular rhythm (6/2 in line 8, 3/3 in line 9), the use of strong words like 'break down' and 'suffocating death,' as well as exclamatory phrases like 'oh,' 'alas,' all convey the intense feeling of suffocation, the desperate longing to escape prison, and return to the freedom of life outside.
The beginning and end of the poem (with the cuckoo’s call) reflect two different emotional states. Initially, the prisoner eagerly anticipates the joyful life outside, while by the end, the cuckoo’s call intensifies the sense of pain and suffocation, making the poet long to break free from the prison and return to a life of freedom.
Line 4: The beauty of the poem lies in both its content and artistry.
– The structure divides the poem into two parts: the first describes the summer scenery, while the second expresses the prisoner’s inner turmoil, blending these elements into a cohesive, emotional flow. The vivid imagery (bright colors, sweet fragrances, lively sounds) conveys an overwhelming sense of life, evoking deep, passionate emotions.
– Rich, vivid imagery with a strong pictorial quality.
