If you enter into Wat Po, there’s a little counter where you can donate money and write your name/wish/message on a tile that they would use for renovating this temple.
You write it down with pencil that they provide on the table.
But then, you walk a little bit, around the tree, and you see this guy doing this…
Uh huh! He’s washing the tiles so that they can use it again! Seesh, at least take some effort to hide it somewhere further away from the table lah. But that aside, Wat Po is still worth visiting.
