主题：【整理】中缅边境记事 -- 从北苑到太古

sorry, i can't type chinese.

i think there is probably some sort of road/trail in the forest to connect the camp to the outside world.to build a training camp, it needs lots of material & equipment. to maintain the camp & train people, it also requires lots of supplies & need to transport the people from outside to the camp.

the article also mentions "发现美国武装人员,从中方计划撤退的线路上正在向营地快速逼近". if they moved quickly in the forest, probably they were using some kind of road.

if there is a trail/small road in the forest, then people can move fast.
