I need for transit visa for Guangzhou for two hours.

Alisher, after 2-hour transit in Guangzhou, if you will fly to a third country or region, you will be able to utilize the 24 hour direct transit there. In this case, no transit entry permit is required.
The required documents for transit G type include your passport and its photocopy, the application form, a passport-style photo, your valid entry permit for Malaysia, and the onward tickets.
