云南边防4061公里边界,无天然屏障,国界犬牙交错,大小出境通道无计其数。跨国而居的民族达10多个,语言相通,同文同俗,通婚互市历代不断。一村两国,竹楼跨境而立。由于历史成因和现实的因素,边境线根本无法采用架设铁丝网,辟设无人地带的管理措施。 Yunnan border 4061 km border, no natural barrier, cross-border intertwined, the size of exit passage countless. There are more than 10 ethnic groups living cross-border countries with the same language, the same culture, the same customs, and inter-marriage marriages. One village and two countries, bamboo building across the border. Due to historical reasons and realistic factors, border lines can not be used to erect barbed wire and provide unmanned management measures.
