大道理

Don't preach me a sermon, please.

请不要对我讲大道。

There are major and minor principles in everything, and the minor principles are all subordinate to the major.

事情有大道, 有小道, 一切小道都归大道。

I know my own mind in art appreciation, so don't tell me about conceptualization, symbiotics, and all that jazz.

我对于美术欣赏有主张，别跟我讲、共生现象等那一套大道。
