These principles are especially true in places like China’s rural Xinjiang province, where life expectancy is stunted at 67 years (compared to 73.5 for China as a whole), and lack of access to health care undermines well-being. Xinjiang covers nearly 650,000 square miles (1.7 million square kilometers), but it is home to only 21 million people, many of whom are members of nomadic tribes.
这些原则在中国农业省份新疆等地区特别突出，新疆人的预期寿命只有67岁（全中国水平是73.5岁），缺医少药抑制了新疆人的福利。新疆面积近65万平方英里，但只有2100万人口，其中许多人过着游牧生活。从经济角度讲，新疆的活力是中国经济增长战略的关键——它被视为中国的西大门。
