I WANT TO KNOW IF I CAN APPLY FOR THE TWO ENTRIES VALID FOR 6 MONTHS

I HAVE ALL THE NECESSARY INFORMATION FOR MY VISA EXCEPT. I WILL BE IN CHINA FOR 73 DAYS AS I WANT TO GET IT EARLY AND IF I SAY 3 MONTHS FROM DATE OF APPLICATION I MAY NOT HAVE ENOUGH TIME. I AM LEAVING ON NOVEMBER 24, 2013 AND RETURNING ON FEB 4, 2014 AND WOULD LIKE TO APPLY FOR IT IN OCTOBER 2013. THANK YOU IN ADVANCE FOR YOUR REPLY
