This study takes the historical evolution of Chinese orchestral music as the research background, elaborates on the main instruments of orchestral music and their roles in early Chinese orchestral music, and vividly interprets Mr. Li Delun's good creative and directing skills. In addition, the creative connotation of orchestral conductor proposed by Mr. Li Delun and its important contribution to the exchange and integration of Chinese and Western orchestral art were introduced. Finally, this study introduces the future development path of orchestral music from the perspective of the era's challenges and market orientation in the development of symphony. The research results indicate that the creative style of a music conductor, as an art form shaped by their unique personality, is the result of the fusion of their inner emotional experience and the simulation of their creative source. Symphony orchestras can continue to conduct research and practice in fields such as online music and concerts. As an outstanding artist, Master Li Delun not only possesses rich creative knowledge and skills, but also emphasizes that conductors should master the music theory and practical experience of the band, including music history, stage design, theatrical performance, literary research, and philosophy. For the government and cities, the continuous progress of symphonies and their bands is a long-term social welfare activity that helps to shape a good social atmosphere and improve the cultural and educational level of the public. Therefore, the government should provide necessary financial assistance and policy support for symphony orchestras.
