First, the City of Seoul thinks this is scenic:
Dudes.. that's a ROAD!
Second, only in Seoul do trees get intensive care, in this case some kind of restorative drip. This was in the area of Bukchon and I hoped the sign would give me some help, but it's just a request that the cultured citizens of Seoul not leave trash in front of a gallery.
But, I should say, the trees looked splendid and thus the medical care is probably warranted. ;-)
