What do 切入点 and 突破口 mean? Today I hear the news on radio that the pollution work in Hebei, China deteriortates when some public officers are involved in the scandal of discharging polluted water. Then an official of the local environmental authority said when interviewed by media that 我们将以XXX为切入点，以治污XX为突破口(sorry, some words are beyond my understanding), I think my script is nearly perfect or accurate, but what they mean really I like to hear what you say.
切入点: starting point, point of view

突破口: point of breakthrough

For example:

我们将以工业排放为切入点, 以污染源头为突破口.

(We will take industrial emission as our starting point, the source of pollution as breakthrough.)

爆米花理论似乎是一个无聊的切入点.

The theory of popcorn might seem a boring view.
