学习英语，还是要多读。

In February, the nation boasted 550 “million-dollar” cities where the median home value was north of seven figures, up from 491 a year ago, the analysis shows.

North of? 什么意思？在七位数的北面？

No，North在这里的意思是“高于、超过”的意思，above (a particular amount, cost, etc.)

问题来了，那south呢？

当然是“低于”的意思啦，below（a particular amount, cost, etc.)

英语是一种很操蛋的语言
