Introduction
My name is Guoyou Sun. I go by G. Sun or G. -Y. Sun for short. Sun is my surname and Guoyou is my given name. Chinese names are written in surname-first order. Hence, my name should really be written as Sun Guoyou (孙国佑 in simplified Chinese, 孫國佑 in traditional Chinese).
I was born in 1984 at Yueqing City, Zhejiang Province, P.R. China. I’m an amateur astronomer with a passion for discovering new objects, and a member of the Chinese Astronomical Society and the Xingming Observatory Sky Survey team. I won the 2015 Edgar Wilson Award for the discovery of comet C/2015 F5 SWAN-Xingming, I am priviledged to be named after asteroid (546756) Sunguoyou.
