What do Chinese college graduates have in common with ants? The recent         Ants Tribe about the lifeof some young people         flock (聚集) to Beijing after        university, describes the graduates, like ants, as smart but         as individuals, drawing strength from living together in communities.

The book, which is based         two years’ interviews with about 600 low-income college graduates in Beijing,         in mid September, about a month before an announcement from the Ministry of Human Resources and Social Security that 74% of the 6.11 million new graduates had been         by Sept. 1.

For the book’s chief editor, Lian Si, a professor at the University of International Business and Economics in Beijing, that piece of statistic says        about the real situation for many of these graduates. “I am always         how many of these employed college graduates are leading a decent life,” Lian said. “I hope this book could offer a window on these graduates, whose stories are         known.”

The setting of the book is several so-called “settlement villages for college students” on the outskirts of Beijing,         large number of college graduates        . Most of these graduates work for         or medium-sized businesses,         less than 2,000 yuan a month. They live together because it’s        : the rent in these communities is only around 350 yuan a month. Many of them travel several hours a day for short-term jobs or job interviews.

Tangjialing, a small         20 kilometers from Tiananmen Square, has around 3,000         villagers, but has become a         for more than 50,000 migrants, most of them         from all over the country. Lian describes the students’        as five-or-six-storey buildings with two or three people crammed together in each room of about 10 square meters. Up to 70 or 80 people share the same toilet and kitchen.
