Zheng Kelu Maurice Maeterlinck (Maurice Maeterlinck, 1862-1949), a Belgian symbolist dramatist.Born in a family of notaries, he studied law in his early years. After graduation, he went to live in Paris and met some friends who admired symbolist poetry. From then on, he determined his literary career and creative tendency.His first work, Greenhouse (1889), is a collection of symbolic poetry.The play "Princess Malena" published in the same year received the attention of French critics. This play was the first time that symbolism was applied to drama creation.Since then, Maeterlinck has published plays one after another.The 1990s was the first period of his creation. The most famous work of this period, Peleas and Melisande (1892), is a love tragedy rewritten according to a medieval knight story.From the beginning of the 20th century to his last play (written in 1929), Maeterlinck entered a new stage of creation. In addition to the masterpiece "Blue Bird" (1908), the more outstanding works include "Mona Vana" ( 1902), "The Apparition of St. Anton" (1919) and so on. "Mona Vanna" describes the heroine of the same name who resolutely sacrifices herself to avoid the loss of her life, and "The Apparition of St. Anton" criticizes all kinds of ugliness in fighting for inheritance.Maeterlinck has written more than 20 plays and has become the most important symbolic playwright in the early 20th century. In 1911, he won the Nobel Prize for Literature.

Maeterlinck went against the previous traditional dramatic techniques. His reflection of real life did not use direct and specific descriptions, but went through a layer of symbolic refraction.The novelty of this symbolism lies in the rich imagination: abstract and intangible things are endowed with life and individuality according to their characteristics.This way of describing real life and things in nature is quite thought-provoking, giving people scientific and philosophical thinking.He is full of sympathy for the lower class people and resents the injustice in the society, but this kind of sympathy and injustice is a bit resentful but not angry. The work has a soft and warm color.And his disappointment with reality led him to take a pessimistic attitude towards the fate of human beings and accept the mysticism.However, his later creations overcome these weaknesses and reflect a wider range of social life.

"Blue Bird" is such a work.It reflects the author's sympathy for the life of the poor, optimism and vision for reality and the future through the story of two children looking for the blue bird.Various symbolic techniques with meaningful meanings are used in the play.The blue bird contains several layers of symbolic meanings. It is a unique embodiment of human happiness, and it also contains the mysteries of nature. Therefore, it embodies both the spiritual happiness of human beings and the material happiness of human beings. To real life, but also related to future life.The author uses concrete things like bluebirds to represent abstract concepts. He wants to explain that human happiness exists. Although we can't find it because we think it is far away from us, we can finally find it after going through all kinds of difficulties and dangers. And what is lost can be found again.This kind of symbolism seems to have a stronger artistic effect than positive statements.In the play, various tangible and intangible substances, various animals and plants, various thoughts and emotions, various social phenomena, even abstract concepts and future things are anthropomorphic, giving people concrete and vivid inspiration.It has the beautiful poetry of fairy tales, but ordinary fairy tales do not have its profound philosophical meaning.These are the success of the drama "Blue Bird".
