What is the difference between "举行" and "举办"? Both of them have the meaning of 'holding / organizing an event", but do they have any difference?
An answer I found on Baidu Zhidao says this:
The difference between the two words can be seen from the words themselves, “行” focuses on the process of events, while “办” emphases the thing things and the carrying out of such things themselves (meetings, competitions, etc).
The following all use "举行"
The following, here, would all use "举办"
So basically 行 = just doing it 办 = includes setting it up and doing it (edit: or organizing like you said in your original post)
