What's the structure of these words? 搬进、走出、跑回......
I think both 搬 and 进 can be verbs but when used together, it means 'move in'.
What's the relationship between the two characters in phrases like those?
For example, only 搬 is the verb in the sentence ‘我们搬进了一幢楼房’，but not ‘进’，what is the role of ‘进’ in the sentence?
