I want to know the answer to the following question:
During what dynasty was Nanjing the biggest business center in all of East Asia?
All the background I'm provided with is that "Textiles boomed particularly in Qing dynasty, the industry created around 200 thousand jobs and there were about 50 thousand satin machines in the city in 18th and 19th century.". Is that enough to answer the question?
Answer: no
