Words for "thing"? Different usages? 办法说“事情“或者”东西“？用的时候是一样的吗？ I know a few words for "thing“， including 东西 and 事情. I've looked online, and haven't found any other commonly used words, or indication of when to use which. Are they the same? Is one more formal than another? Is there a better, more formal word I should use? Or is the word "thing" just not used a lot in Chinese?

对不起，我的中文不好！这是我最好的翻译。

我知道一些办法说“东西”或者“事情”的意思。我查资料在网上的时候，不会找到了其他字（除了东西和事情以外），也没找到了什么时候应该用”东西“或者”事情“。是一样的吗？一个是比较正式的吗？还是中国人就不常用“事情”或者“东西”的意思？谢谢大家！
「事情」refers to an event or situation. I wouldn't translate it as thing; the only situation where thing is an acceptable translation is something like

他辦事情去了
He went to take care of something

But something could have easily been substituted with a situation.

I disagree with the other answers here; there are several things that are abstract but  which can be referred to as a「東西」.

感情是個很奇怪的東西
Emotions are a very strange thing

You cannot replace this with「感情是個奇怪的事情」, which doesn't make sense.
