Introduction to the China Aviation Pavilion: The appearance of the pavilion is derived from the changing "clouds", suggesting human beings' dream of flying in the blue sky; it also resembles an infinity symbol, symbolizing the infinite mystery of the universe, providing infinite possibilities for aviation development, and also implying that flight brings prosperity to the city The infinite changes brought about by this, hence the nickname of the exhibition hall "Flying Infinity". The exterior of the exhibition hall is covered with pure white membrane material, which brings the association of "cloud" into the eyes of visitors, thereby expressing the concepts of "flying" and "soaring".
