Long distance relationships are tough. When our sweetheart's far away from us, we can't hold their hand, we can't cuddle with them, and we can't even be couch potatoes together and binge our favorite Netflix titles. We miss them so much, we might feel like crying sometimes. Thank goodness for the internet and for smartphones, right? At least nowadays we can reach out and (virtually) touch someone when we really miss them.

Now, imagine being in a long distance relationship a thousand years ago, when there weren't any phones, there wasn't an internet, and we didn't even have cars and planes to zip us around. Li Po's "A Poem of Changgan" gives us an insight into exactly what it felt like to be in a long distance relationship before technology made it easy for us to stay in touch. It's a poem that's spoken by a young wife who's waiting for her husband to return from a long journey.

Even though "A Poem of Changgan" describes a time and a place that may be very alien to us (it's set in China, and was written over a thousand years ago, in the middle of the eighth century), the feelings that the poem describes are very familiar. The young wife's sadness, her isolation, her feelings of missing her hubby are all things that many of us have experienced when we're separated from those we love. Sure, nowadays we have technology to help us stay in touch, but there's no getting around the "distance" part of a long distance relationship.

Ah, first love—we know the feeling: when that special someone in our chemistry class walks into the room, and our heart starts pumping. Our hands get all sweaty. We get all fidgety and nervous. It's like we're possessed. There's nothing like that experience of falling in love for the first time. Chances are, even if we go on to have a hundred girlfriends or boyfriends, we'll never forget that first special someone we fell in love with.

Li Po's "A Poem of Changgan" is so great not only because it describes exactly what it feels like to have that experience of first love. Sure, the poem is also about what it feels like to be in a long distance relationship. And yes, maybe we've gone through so many broken relationships ourselves that we've become all cynical about love. But still, "A Poem of Changgan" takes us back to that experience of our first romance—the thrills, the aches, the obsession. And don't we all want to remember what that was like?
