I'm trying to get the meaning of the following expression: 爱惜花草树木. A Chinese friend told me that it's something like "It's so corny", but I'm having a hard time finding an explanation online. I've found a few Chinese websites but the explanation Chinese is way too hard for me :-/
In simple terms it means to treasure nature. It literally means "love and treasure flowers, grass, trees".
You'd generally find it on park signs so that it's a catch all for people not to trample on grass, to not pick flowers, wreck trees, that sort of thing.
