夏天弃了西瓜爱上了空调
[xià tiān qì le xī guā ài shàng le kōng diào]
Translates to 'Summer has abandoned watermelons and fallen in love with air conditioning'. It humorously reflects the tendency for many to rely heavily on air conditioners during hot summer days rather than traditional summery activities. This can also refer to changing preferences over time.
