This is a slogan. It means ‘Reading books is the best investment whole my life.’ Why is it there?
This one is hanging on the building’s front door. That building is located in the riverside nearby my home.
It said in the building there are many books, so if you want to read a book, come inside during a walk though the riverside.
I think it’s very interesting one because walking and reading are not similar one. The former is outside activity but the latter is inside activity. Therefore I think it’s little bit weird one.
What’s your opinion?^^
