Yes we only have the wet and dry season in the Philippines.
In the private cemeteries you will buy the lot for the burial and it will be yours but for a really big sum specially when it's at need. Some offer payment terms until you have paid it in full. Then you'll just to maintain the lot like if it's on the garden area like ours we have someone tending the grass.
For the public cemeteries I think there is a certain date that you can use the vaults. Then if they are not maintained after ten years or more they will get all the bones and place them on like a community burial site.

I will try posting different photos that have different themes in them.
Thank you Ms. Erikah learned something new again from you.
Grateful to be one of your follower.
