he Memorial Hall is white with four sides. The roof is blue and octagonal, a shape that picks up the symbolism of the number eight, a number traditionally associated in Asia with abundance and good fortune. Two sets of white stairs, each with 89 steps to represent Chiang's age at the time of his death, lead to the main entrance. The ground level of the memorial houses a library and museum documenting Chiang Kai-shek's life and career and exhibits related to Republic of China-era Chinese history, and Taiwan's history and development. The upper level contains the main hall, in which a large statue of Chiang Kai-shek is located, and where a guard mounting ceremony takes place in regular intervals.
