Collecting my Z Working type in Hong Kong

Dear Sir/Madam,
Thanks for providing with helpful assistance.
I'm an Italian citizen who got offered a position in Shanghai so i'm on my way to collect all my papers to get the Z working type. here you have my questions:

- I'm applying the Z type by submitting my school diploma (it's English based). my visa agent says it doesn't have to be translated in chinese , can you confirm it?
- I will have to fly to Hk in the next 10 days so i won't be able to collect my Z type from the Chinese consulate in Italy. do you know if it's possible to collect my passport with the stamped entry permit in the Italian consulate in Hong Kong?

thank you
