Tourist Visa application

I'm a Malaysia citizen, currently residing in Australia. I booked a flight to Nanning, China on 9th December to travel with my partner who is a Chinese citizen. I'll be flying off to Malaysia on the 1st of Dec and planning to apply for a Chinese visa in Kuala Lumpur. Am I able to get my Visa on time?

I also read the website that I needed to show a confirmation of hotel reservations before applying, I'll be staying at my partner's relative house when I travel to Nanning. Is there any other document that I can provide?
