The purpose of this study is to compare the symbolism of Tea, the central material, and crane , the subsidiary material, in the poem of Lee Kyu-bo and Kim Si-seup. The reason why these two were selected as comparison targets is that they lived in different times but lived in upheaval of the times. Lee Kyu-bo was a writer who was active during the military coup d'état and was a reality-oriented and practical person. Kim Si-seup was a person who resisted the existing regime by living a life as a foreigner to protect his religion and fidelity as a Confucian scholar during the Gyeyujeongran period. For Lee Gyu-bo, who was reality-oriented, the tea was a medium of mental evocation while living in a reality that could not leave. For him, the symbolism of the crane was a medium to enter the Zen world , the ideal world that Lee Kyu-bo aimed for, and it appears as a subject that represents his mind that he wanted to go to the transcendent world he dreamed of through the crane in the reality that he could not escape. For Kim Si-seup, tea was also a medium to comfort his longing for and anguish over the reality that had left him. For Kim, the symbolism of the crane represents a Taoist symbolism, but it can be seen that it emerges as a spiritual symbol that symbolizes the fidelity and incision of the Confucian. The symbolism of tea and crane in the two's class is a universal subject of oriental literature, but it can be confirmed that it is an important subject that can confirm the attitudes and values of life in the circumstances of the times.
