1. "On the side of the water" comes from "Jiang Jia" in "The Book of Songs, Guo Feng Qin Feng". "Jian Jia" is a classic love poem, which describes a man's pursuit of the person he can't get, "Beside the water" symbolizes a life situation that is elusive and out of reach.
2. The original sentence is: Jianjia is green, and white dew is frost. The so-called beauty is on the water side. If you follow it back, the road will be long and blocked. Traveling back from it, Wan is in the middle of the water. Meaning: The newly born reeds by the river grow extremely lush, and the autumn dew condenses into white frost. The person I yearn for is on the other side of the water. I went up the river to find her, but the journey was full of hardships and dangers and it was very long. Follow the river to find her. She seems to be in the middle of the water.
3. This is a beautiful lyric poem. The whole poem uses images such as Jian Jia, white dew, and river water to describe a man's pursuit of the person he wants but cannot get, creating an ethereal and ethereal artistic conception. When later generations understood this poem, they also interpreted various symbolic meanings into the poem.
