I am actually required to get my academic qualifications certified by Chinese Embassy in Malaysia.

As for the degree, you should first get it notarized by the Ministry of Education, and then get your academic qualifications and its translation certified by the Ministry of Foreign Affairs of Malaysia, Putrajaya and then go to the embassy of China to get that attested; the required documents include your passport and its copy, the application form for attestation, and your academic qualifications and the copy as well as others.

May I know where do I get the attestation form?

Try to check the official website of the China embassy in Malaysia to find that.
