Quotes from the article linked to above:
"One of Wu's prize-winning works was a 1:35 scale model M32B1 ARV (armored recovery vehicle) which was used by the US Army during World War II. Beside the model of the rusty vehicle stands a soldier figurine."

"Last year, Sun won third prize in the 16th NAVIGA World Championship in Croatia. His winning entry, a 1:350 scale model of the Japanese battleship Nagato from World War II, will be on display at the first floor of the Shanghai Mass Art Center till January 15."

"For 22-year-old Zou Xiaomin the event was more onerous. Although he is comparatively young among the city's leading model makers, he has already gained a reputation as a leading creator especially of characters and themes from the Japanese comics The Five Star Stories. "
