I want to know the answer to the following question:
Who was known as China's greatest poet and lived in Chengdu?
All the background I'm provided with is that "Sichuan came under the firm control of a Chinese central government during the Sui dynasty, but it was during the subsequent Tang dynasty where Sichuan regained its previous political and cultural prominence for which it was known during the Han.". Is that enough to answer the question?
Answer: no
