As the themes of the repertoire have expanded, the tunes have also been enriched and developed. In addition to Tanhuang tune as the basic tune, the frequently sung tunes also include Lovesickness at the Fifth Geng, Yipibu, Manjianghong, and Four Great Scenes, etc. . In the 31st year of the Republic of China (1942), He Xianmin, an artist who sang "Xuanjuan of the Ming Dynasty", participated in the "Improved Ningbo Opera" performance at the Hengya Theater. He wrote, directed, and acted in new plays such as "Sister Hua" and created a new opera from the Qing Dynasty. The play transitions to the cusp of the suit and cheongsam play. Together with Xu Fengxian and others, he explored the reform of Ningbo opera music, strengthened the melody of Ningbo opera singing, and changed the old basic tune of 26 tunings to the new basic tune of 52 tunings, making the music of Ningbo opera more lyrical and popular with the majority of Ningbo opera singers. It was welcomed by opera artists and widely used, and it also laid the foundation for the later creation of the "Adagio" singing style of Yong Opera.

However, due to the lack of major breakthroughs in the content of the repertoire of the "Improved Yong Opera" and the limitations of the troupe's own artistic quality, Yong Opera declined day by day after the victory of the Anti-Japanese War.
