Appreciation of homesickness;
In Homesickness, the author focuses on his personal experience in Chinese mainland. The poet uses the montage technique of movies to capture three scenes of "childhood", "growth" and "later" from his life memory, and outlines his unforgettable memory in Chinese mainland, thus writing the poet's homesickness for millions of overseas wanderers.
The author writes homesickness in four stages, with time as the order and different emotional experiences as the clue. There is a feeling of coming and going freely in neat sentences, and the emotion has also sublimated from simple sadness about hometown to incomparable love for the motherland.
The formal beauty of nostalgia is also remarkable. Its formal beauty: one is the beauty of structure, and the other is the beauty of music. Homesickness presents the beauty from tradition in structure. Unity means relative balance and symmetry; Paragraph patterns and sentence patterns are relatively neat, and paragraph by paragraph and sentence by sentence are relatively harmonious and symmetrical. Change is to avoid unification going to extremes, and to pursue the beauty of liveliness, fluidity and vitality.
