What are the four best words to name Sun Chen?

Sun Chenyu (from Lu You's Butterfly Lovers: The Night Talk of Ye Chen Floating Flies). )

Sun (from Fang Gan's "January Day: Morning Chicken" twice, Diao Doumo did not send it. )

Sun Chenyu (from Du Fu's Morning Rain): In the morning light, I smell it on the early leaves. )

The three-character name is very nice. There is no need to take a four-word name.
