On 23.10.2014, in 南开 Nánkāi University, from a list of 10 actors (shown below), 19 students chose 4 actors/actresses to, as it were, act in a film. The candidates were:
Chéng Lóng 成 龙
Dèng Chāo 邓超
Fàn Bīng Bīng 范 冰 冰
Gõng Lì 巩 俐
Liú Dé Huá 刘 德华
Li Yū Chún 李 宇 春
Xú Jìng Léi 徐 静 蕾
Xú Zhēng 徐 铮
Zhāng Guó Lì 张 国 立
Zhāng Màn Yù 张 蔓 玉
and they used a matrix vote. The winners were Fàn Bīng Bīng to play the role of the corrupt official (25), Dèng Chāo to be the hero (17), Chéng Lóng to be the villain (16) and Xú Jìng Léi the heroine (15). But the interesting fact was that nobody voted for all four actors; and nobody voted for none of the four; so everybody won something and nobody won everything. Perfect. A classic example of win-win voting.
On 9.12.2014, a similar exercise was undertaken in Xúzhōu University. Again, everyone won something and no-one won everything. This is the full analysis.
