Combination of fan and umbrella

First of all, these two objects are related to weather phenomena. "Fan" means it's hot (sunny) and "umbrella" means it's raining. There are two main meanings: 1. Sunny and rainy days can be regarded as the extremes of comparison between the two weather phenomena, which means paying attention to the weather changes. It's still so hot in rainy days, which shows that the weather (climate) is abnormal and that attention should be paid to climate change and environmental protection. Besides, the umbrella can also be used as a sunshade. Take these two things with you when you go out, which means it's sunny and hot.
