Is there any way for me to get China visa if my ARC has been just for less than 6 months?

I'm invited to go to Shanghai for Poster Presentation in International Conference this June. But as I mentioned, my ARC is just for less than 6 months.. Is it true that Chinese consulate in Busan issues visas to people without ARC ?

Is there another way? cause this event is very important to me..

Thank you for your assistance..
