Cai Ruizue is regarded as a pioneer of modern dance in Taiwan, and has spared no effort in promoting modern dance. Born in 1921 in Tainan City, at the age of 16, she went to Japan and studied under Mr. Seki Ishii, who was called the "father of modern dance" at that time, laying the foundation of her dance career. After returning to Taiwan, she devoted all her energy to dance, bringing the concept of modern dance to Taiwan. On this land, Teacher Cai created more than 500 modern dance pieces, such as "Song of India" and "We Love Our Taiwan", and integrated diverse dance forms, including ballet, ethnic dance, and traditional Taiwanese folk dance. She was called the "Mother of Modern Dance in Taiwan."
Cai Ruizue Dance Research Society is a historically significant building, an official residence during the Japanese colonial period. At that time, various types of residences were built in the urban area of Taipei, mostly wooden Japanese-style houses. In 1920, dozens of double-row wooden residences were built on Zhongshan North Road. The Cai Ruizue Dance Research Society was built then, and based on its layout, it was a residence for Japanese officials of the rank of "Punishment Officer." In 1953, it became the home, choreography, and dance practice classroom of Cai Ruizue, the "Mother of Modern Dance in Taiwan," and later evolved into a dance classroom. Although it once suffered a fire, in 1999, it was unanimously recognized by experts and scholars of historical sites as the place where modern dance took root in Taiwan. Therefore, it was firmly rebuilt by the community, thus avoiding the speculation of real estate developers, and the life of the historical building was thus preserved.
