Jet Fighter - Gate of Nanchang HangKong University

Nanchang HangKong University (Aviation University) has a number of PLAAF aircraft on display at its main gate. This one takes pride of place. I've no idea what this is, whether it's a Russian design or an indigenous Chinese design.
I believe, though I'm not 100% sure, that China's first jet fighter was designed and manufactured in Nanchang.
