Why do mainlanders prefer the weather in Guangdong to that in Jiangsu?

It is changeable. Since the spring before the Meiyu period in 2022, the weather and climate in Jiangsu have changed greatly and the disasters have been serious. Guangdong is only cold (very cold) and hot (hot and humid in summer), and the temperature changes little, so mainlanders like the weather in Guangdong and can't adapt to the changes in Jiangsu.
