Hi Mike, it is great to know that you are learning Chinese. In my opinion, I think you don't need to worry about it too much. Though there is a cultural difference and different ways of expression, as long as you are being polite and friendly, you have nothing to worry about. However, try to avoid talking about highly sensitive subjects like politics, religions, and so forth, which might cause arguments. Anyways, happy learning! And if there are any specific circumstances you would like to talk about, I'd be happy to share more tips:)

景象： view； omen for example 窗外是农民们丰收的景象。(Outside the window is a sight of the farmers harvesting ) 情景：circumstance; context; feeling and scenery 这张照片让我想起了当年的情景！（This picture reminds me of the old times!）

you could say: 我把他狠狠地教训了一顿 or 我把他打得很惨。
