It's a long way. Xiu Yuan can see the moon, but it's a long way. What does it mean that Xiu Yuan can see the heart?

Looking at the moon for a long time and looking at our hearts for a long time means that we can look at the moon again and again during the long journey, but only when we are with friends who have been through the battlefield can we really understand their hearts. According to the relevant public information, "Seeing the bright moon on Wan Li Road, seeing each other with foam and seeing the true heart" is an ancient poem, which comes from "Farewell to Ancient Grass" by Bai Juyi, a poet in the Tang Dynasty. This poem expresses two meanings with the metaphor of the moon and friends. On the one hand, the moon is a daily natural phenomenon, which often appears in our lives. People can see different moons through different positions and times.
