comment What is the difference between 通常,经常,and 常常?
So, going by your example sentences, it seems that 通常 is used for statements that happen frequently, both past, present, and future. But, is it ok to use 经常 in your sample sentence, like "事情经常是这样的“. If it is ok, do these two statements imply any difference in the frequency of an event?
