This year 300,000 more Chinese students will step out of universities compared with last year, but more of them are less anxious to get employed. College graduates have multiple choices now, including starting their own business, applying for higher degrees, etc. The number of college graduates who chose to start their business amounted to 200,000 in 2015, indicaing the strong momentum for mass entrepreneurship and innovation in universities.
