In the formal survey, 431 undergraduates from different grades and majors took part in the research in the unit of class （ 151 males and 256 females）. A neutral background material of about 1000 words was edited on the news from Sep 7th to Oct 20th of 2012. The questionnaire included national identity, three types of group-based emotions, t
