This is from the Standard Course Book of HSK5, section 15.
Baidu and Google say that here 我 means we and indeed according to dictionaries 我 not only means I, but it can also mean "we".
So when should 我 mean I and when we? And what is the difference between 我 and 我们 as we?
Simply, the context determines when the 我should mean I and when we, and 我 as we is just the short version of 我们? Or is there another rule we should know?
