I am Malaysian. do i need visa for this travel?

Yes, you need an L type for the travel. To begin with, please prepare your passport, a photocopy of the info page of the passport, a printed application form glued with your recent color bare-headed photo, and itinerary proofs, like round-trip tickets and hotel booking orders, or an invitation letter from a relevant individual or entity in China. Then take the documents to the CVASC center and submit them.
