Personally, I think the lake of life can refer to a place that accepts, understands and nourishes you in a person's life, a holy place that keeps life alive and a spiritual support.
Red poppies may imply a noisy, impetuous and nihilistic illusion, but it is a beautiful illusion in an instant. You pass by it, feel it, say goodbye to it and continue your journey. It may make your life colorful, or it may consume you or even destroy you.

Original text:
Let's go, the fallen leaves blow into the deep valley, but the song has no home.
Let's go, the moonlight on the ice has overflowed from the river bed.
Let's go, eyes looking at the same sky, heart beating the drum of dusk.
Come on, we haven't lost our memories. Let's find the lake of life.
Let's go, there are red poppies on the road.
