I wrote an email to the consulate explaining my situation.  I said that because I have to move back to the US for a job, I believe I have met the requirement for DCF under 

"Short notice of position relocation – A U.S. citizen petitioner, living and working abroad, has received a job offer in or reassignment to the United States with little notice for the required start date."

They later sent another email asking  three questions. 
 

• Please explain the reason you would like to file directly with the Consulate and are unable to file directly with USCIS in the United States.
• Have you already filed an I-130 for your beneficiary directly with USCIS?
• Please confirm that both you and the beneficiary are currently present in China, and will be able to remain in China for the duration of the immigrant visa petition filing and immigrant visa application process.

After I answered these three questions, they sent me a date for an interview and to submit I-130.

On the date I as the petitioner went to the interview, and hand delivered I-130. I was also asked basic questions, of how I met my wife, how long have we been together, what job and company was I going to work for, lastly when will I return to America. 

Hope this helps.
