F-7s in Pakistan

hi,everybody

I m a Chinese,now in Beijing. there are 2 questions I want to ask

1,I m very interested in the performance of PAF F-7s. Can anyone tell me about it? Have any PAF F-7s deployed in the Pakistan-India conflict? and have any F-7s shot down any IAF airplane? or have any of them been shot down?

2,I heard that in 70’s, Libya had employed some 3,000 Pakistaners as “advisers” can anybody tell me some details? any of them deployed in
Al-Qathafi’ war?

thanks in advance
