WK sometimes makes obscure references to popculture/history/etc to help us remember readings, right? I feel like they missed out on a great opportunity with the vocabulary word: 波. Here’s the explanation they provided for the reading:
You jump on a wave and ride around the world on it. It doesn’t drop you off anywhere, until you reach a certain location: Vietnam (なみ). You jump off the wave and look at Vietnam. Imagine the most Vietnamese things you can think of to help you to make this wave-Vietnam association.
Have they not seen Apocalypse Now? The absurd scene of surfing in Vietnam in the middle of a war is imbedded in my brain.
