All the locals go all over these areas collecting mushrooms, bamboo shoots, pak wan ( dont know english)
Honey comb,
Shooting birds pheasant, other small birds,
Trapping small tree squirrels, moles,
pangolin, tortoise, etc
A few years a land owner, set up an operation,
One of these caves or tunnels had a large population of bats, the cave was just up the hill side from the railway at Lumsum, wangpo viaduct, sapan molanar
The workers employed were to bag up the bat droppings, this was to be used as fertiliser, but then to get it down the mountain side would be difficult,
Thai idea,
A path was cut down the mountain side,
And a zip wire was put up and the bags slided down.
