The Snow Lotus Blossoms is a solo hulusi piece composed by Mr. Li Chunhua around 2007, and was included in the Hulusi Bawu Grade 10 Examination Collection of the Hulusi Bawu Professional Committee of the Chinese National Wind Society in 2009.
From the key customization of the original score, the piece needs to be played with G key hulusi.
However, it can also be played in B-flat.
As long as the hulusi is in the same key as the accompaniment, it is fine.
