SEM Alumni set up its official microblog on sina.com on 1st March, 2013. The microblog catches so much attention that one of alumni of SEM told us online: “We’ve been waiting for so long for SEM’s official microblog. It is very important for our schoolmates.” As an official microblog of SEM Alumni, it is devoted to becoming the exchange platform for SEM’s alumni. With the support from SEM, the official microblog releases dynamic news of Tongji and SEM and tries to improve the social influences of the college. Meanwhile, it offers information on career and employment, demonstrating its public welfare service in microblogging.
