Explanation:

In the poem, 'Grandma Ling' the speaker Amy Ling stayed in Pennsylvania. She was then told that if she dug a hole in her backyard she would reach China. But she goes on to say that she was not strong enough to do that. The speaker waited for twenty years and finally sailed to Taiwan. It is in Taiwan that she finally meets her grandmother for the first time.
