Indian National with British Bachelors Degree willing to apply for China Work Visa

Dear All,

I am an Indian national, currently living in China.
I hold a Bachelors' degree from UK.
I would like to apply for Work Visa. As per my knowledge, I need to attest or notarize my degree certificate document from the Chinese Embassy in UK.

Please clarify my above doubt.
Secondly, help me go through the process of getting this document and any other documents required for applying the work visa.
Thanks!
