Love locks

Andy

Me and my wife do it every year on our anniversary on the bridge that I proposed to her on. In total there's 25 locks of ours on there to date. 

Never done but I agree I think it's kinda like polluting it in a way 

Nora

I never put this. I don't have lover. Haha

I've never done it myself, but I remember seeing this whenever I visit Koreatowns around the world. I thought it was for couples, but I noticed that their version is also for their family, wishing them good health and prosperity. If that's what it is for, I am all for it.
 
Also, I noticed that Koreans and Japanese, not Chinese, respect public property. They do not do this anywhere but only where designated. I have seen this done on bridges like this, and they are nothing but an eyesore.

It is a romantic thing to do...I tried to do it at a wired fence and hopefully they didn't remove it...I will check to see if it is still there.

I haven't done this

I don't like seeing it on this gorgeous bridge for sure.  I wouldn't personally do this.

Never done that, but I've seen it

I've never done it, and have only ever encountered this as a tourist attraction. In Korea, by Namsam Tower, there's a designated area to do this. People visit the tower, attach locks, and generate revenue for the area.
