online appointment for China visa application in CVASC

Hi Guys! I've bought tickets to China for the 19th of Jan and I;m slightly cofused about the visa application system. On the website the online appointments are booked out and the site doesn't let you look at February's availabilities. I also filled out the on-line application and once i complete it does it process by it self or do I need to go to the CVASC to process it?
