From the perspective of Eastern philosophy, Haichang Polar Oceanarium can be interpreted as a space that embodies the concept of "harmony between man and nature". In Eastern philosophy, especially in Taoist thought, the harmonious coexistence of man and nature is regarded as the highest state. Haichang Polar Oceanarium simulates the polar environment and allows visitors to get close to marine life. This experience is not only a visual enjoyment, but also a spiritual touch. It reminds us that humans and other creatures in nature are interdependent. We should respect and protect nature and achieve harmonious coexistence between humans and nature. This harmony is not only reflected in the interaction between humans and animals, but also in the protection and respect for the natural environment. From the perspective of Western philosophy, especially existentialism, Haichang Polar Oceanarium can be interpreted as a place to explore the meaning of "existence". Existentialism emphasizes individual freedom, choice and responsibility. In the oceanarium, facing those free-swimming marine creatures, people may think about the meaning of their own existence and the relationship between humans and other life forms in nature. This experience prompts people to reflect on their own lifestyles and the impact of human activities on the natural environment. At the same time, every creature in the aquarium exists in its own way, and their existence reminds us that every life has its own unique value and meaning, which echoes the individual uniqueness and free choice emphasized in existentialism. Whether from the perspective of the "harmony between man and nature" in Eastern philosophy or from the existentialist perspective of Western philosophy, Haichang Polar Oceanarium is not just a place for entertainment and education, but also a philosophical space that triggers people's deep thinking, promotes harmonious coexistence between man and nature, and explores the meaning of life.
