Taiwan 2025 - NE Coast, Temple Incense

One of these days I'm going to ask what the big incense stick symbolizes as compared to the dinky ones surrounding it.  Surely the monks working in the temple itself are the ones that put it there.  Is it one per day, or will it last a little longer?  Does it convey a greater spiritual significance, considering its probable source?  Is there a special ceremony each time it's installed?  Chenjean has some relatives that are pretty deep into this thing, so will ask one of them someday...
