Why does Xu Wei guitar have a blue flower?

Legend has it that there is a kind of blue lotus in Tianshan Mountain, commonly known as blue lotus, which can come back to life, because it blooms on the cold snow-capped mountains and is also regarded as a symbol of loneliness, purity and freedom. The blue flower on his guitar is the blue lotus, which is also the name of his song.

This song expresses respect for Master Xuanzang, and the whole song has a deep Zen meaning. When he wrote this song, he was struggling with depression. In traditional culture, Xu Wei was inspired by saving lives, so he copied this song and this flower on his guitar to represent his new life.
