This is the first time I've seen Chinese graves. Apparently on the 7th month of the lunar calendar year, Chinese families will come out and tend the graves (clean them up and stuff). The other thing about living on an island is that space is at a premium, so graves are exhumed every 10-20 years or so depending on the plot. There were also Muslim and Christian graves here.
There's a lot of local wildlife... we managed to spot a roughly 4 ft long lizard (monitor lizard?) and a pack of wild dogs (they looked more like huskies than coyotes with their long curly tails).
