The sun is always shining when it's raining 呢句說話有咩意思?

I believe it's a motto that encourage people to be positive when encounting any difficulties(analogy to raining).

I think it is both shining shining and raining at the same time.

(It is raining although it is shining.)

我想它是利用了反語諷刺某些人吧..

如果照字面解釋的好像沒什麼理性可言..

還要利用"always".. 中文即是經常,

大陽怎會經常在下雨時光亮呢?

意思是

"太陽總是光亮的當它正在下雨"
