Mysterious lighting and a picture of trees and buildings

This place is called Jung-gu Office in Incheon, 

which is located in Korea. 

There is also Incheon Airport in Jung-gu.

Jung-gu, Incheon is also a place that contains the past. 

It is also a place where the buildings 

and historical buildings of the past were restored well.

I saw the lights shining on the tree as I passed by that place. 

The color and background are very mysterious, so I took a picture of it.

What do you think?

What kind of insight do you think these lights give?
