The study looked at how rainfall patterns in China changed from 1973 to 2016. They found that while the total amount of rain stayed about the same, the number of rainy days decreased, but the intensity of rain increased. This means that even though it didn't rain as often, when it did, it rained harder. The study also showed that some parts of China got wetter, while others got drier. Overall, the way rain falls in China has been changing over the years, with some areas seeing more rain, and others less.
