UK Degree Attestation for China job

Dear Team,

Please can you kindly help as I am getting very confused regarding an important matter.

I have been offered a new job in Shabghai to start as soon as I obtain my Work Permit and Z Visa. I am British and live in the UK with British Passport. I am a Kindergarten Teacher. I will be working in a kindergarten.

I had my Degree attested by the Foreign Commonwealth Office for Saudi Last year. Will I need to have it re-attested agai for China again by the FCO now? Also, do I need to contact my issuing University again. They certified my Degree as an original document.

Thank you for your kind help with this matter.

Mrs Madison
