I want to know the answer to the following question:
What area of China has the least amount of sunlight?
All the background I'm provided with is that "Under the Köppen climate classification, the Sichuan Basin (including Chengdu) in the eastern half of the province experiences a humid subtropical climate (Köppen Cwa or Cfa), with long, hot, humid summers and short, mild to cool, dry and cloudy winters.". Is that enough to answer the question?
