Today's research on Chinese music technology is mainly focused on three aspects: data collection, music deconstruction, and music reconstruction. In this paper, a general method is proposed to collect Chinese music in the form of numbered musical notation, and a Dizi dataset is collected using this method. Based on the collected Dizi dataset, we conduct research on the Dizi music styles of the Northern school and the Southern School. Characteristics include melody and playing techniques of the two different music styles are deconstructed. A reconstruction example, music style transfer which includes melody transfer and playing techniques transfer is given and audience evaluation is done to evaluate the reconstruction results.
