style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="white-space: normal;box-sizing:

border-box;">研究发现，<span style="color: rgb(255, 76, 0);box-sizing: border-box;">在中国全部36个直辖市、省会城市和副省级城市中，仅有两个城市的功能性城市地域与行政边界较为吻合，即大连和南京</span>。</p><p style="white-space: normal;box-sizing:
