Albacookie, glad to see you here :)
Well, I assume that you will fly by China Southern from some Southeast Asian country via Guangzhou and Urumqi to Vienna and your flight from Guangzhou via Urumqi will be on CZ6021. Right?
So, if I'm right, you have to calculate your entire transit time in China, from your first scheduled landing, in your case in Guangzhou, until your final scheduled departure from China, in your case from Urumqi. If your entire transit time is less than 24 hours long, you will be eligible for 24 hour visa free transit and you don't need any kind of visa. Quite the contrary, if your entire transit time is longer than 24 hours, you will need a Chinese transit (G) visa obtained in advance.
If you have 17 hours layover in Guangzhou, you have to add 5 hours and 25 minutes of flight between Guangzhou and Urumqi and 2 hours of layover there. The total transit time in your case will, unfortunately, exceed 24 hours for just 25 minutes, of course if you have mentioned exactly the length of your layover in Guangzhou.
Please, could you calculate your entire transit time in China once again, very carefully and after you do that, just write your message here, so that we can proceed on discussing your eligibility for 24 hour visa free transit and also for your ability to be allowed to exit the airport in Guangzhou. I can just hope that your total transit time will be ultimately within 24 hour time frame.
