At the beginning of 2005, Xiangyang Primary School actively developed the school-based curriculum resources of local music, inherited the local culture, and carried out the research on the musical characteristics of the local art series of "Children's Singing Sao Zi Song". This topic has been approved by the leading group of provincial education science planning as a provincial topic in 2005. With the development of research, the school organizes students to learn the art of Haiyan Saozi rap, so that students can fully understand the origin, history, development prospects and educational functions of Haiyan Saozi art, stimulate students' beautiful feelings of loving their hometown culture, and make it possible to inherit and develop Haiyan Saozi art.
On June 24th, 2005 and May 24th, 2005, respectively, Zhejiang Provincial Department of Culture and Provincial People's Government issued a document, which listed Haiyan Saozi as a provincial national folk art protection project pilot and the first batch of Zhejiang intangible cultural heritage representative list.
