May i know how many days does the embassy need to make a visa? i am malaysian and now i am currently working overseas. I will only be back to malaysia on 3rd sept(morning) and my flight to china is on 8th sept. i only have 3 days to time for the embassy to prepare the visa for me. Is it possible to get visa in a short time?

If not could i ask my friend to submit the application form for me but i couldn't give the passport because i am using it and i m now working overseas. please advise on this.
