Signese

Is this the title of the poem:

《將進酒》?

I do agree though, 膠樽 is an awfully poetic way to say 寶特瓶.

There is certainly no lack of fog up at the peak. Or maybe I just have really really bad luck, as the couple of times I've been to the peak recently every single time there was lots of fog.

But I agree with you, one should be able to see for oneself that there is fog and not need a sign....

Well this is why I like Cantonese so much.

Yes, that is the poem. It is quite obvious, isn't it?

The fog sign is the remind the driver to slow down, I think. The fog is obvious, but the driver might not remember to slow down.
