Police Celerance Certificate for Z visa

Hello,
I am currently on X type and my studies finished this month and one company they want to hire for in their company. Company asked me to provide Police clearance certificate, my degree attested and Physical Medical report for applying employment licence.

I am in China since 15 months and have't gone to Pakistan. when i applied first time in Pakistan they ask for Police certificate and i submitted already and now this certificate is expires as it is only valid for 6 months.

Do i need to get police certificate again from Pakistan as i am staying here since 15 months?

Thank you for your advice
