I want to know the answer to the following question:
What was Nanjing's GDP ranking in all of China for 2013?
All the background I'm provided with is that "Nanjing's Gross Domestic Product ranked 12th in 2013 in China, and its overall competence ranked 6th in mainland and 8th including Taiwan and Hong Kong in 2009.". Is that enough to answer the question?
Answer: yes
