I travel to China, can i do my travel visa in Malaysia?

If you want to apply for a China visa in Malaysia, you should provide the original and a copy of your permanent residence or work permit for Malaysia which should be valid for at least half a year (except for those who are visa or permit exempt for residing or working in the Malaysia).

how about if i dont have malaysian residence permit? bcos i just want go to Malaysia holiday after that go to china..

You can't get a China visa in Malaysia if you just go to Malaysia for holiday, please apply China visa in Indonesia.
