In a church in the western Ukrainian city of Lviv, Tseng Sheng-guang's mother takes one final look at her son, laid in a casket.
She's joined by other relatives and a number of Ukrainians wishing to pay tribute to a man who died thousands of miles from home, fighting for a country he had never visited before.
"Sheng-guang my boy, I want you to know that you were very brave," she later says. "You will always be my baby and I'm proud of you."
