"Once Slow" is a lyric, composed and sung by Liu, and adapted from the poem "Once Slow". Liu 2065438+2005+65438 sang for the first time on the variety show "The Second Season of Chinese Good Songs" on June 6th. Later, it was included in Liu Huan's original album "Whatever You Want" released on August 7th, 20 15. The song "Once upon a time was slow" is good at imagery. Compared with the increasingly fast world, the slow rhythm of keys and locks, the color of the sun, horses and mail directly translates into a kind of beauty, a kind of goodness, a simple delicacy and a philosophy of life.
