It can only be accompanied by green waters and green mountains: the metaphor of "green waters and green mountains are always there" is timeless. It is also a metaphor for a long time, used when saying goodbye. There's plenty of time. Let's meet again later.

Say goodbye to ancient and modern heroes: "Green hills remain unchanged, green waters do not flow, goodbye." A bow action, agility and agility, a turn, and the free and easy personality of heroic sons and daughters are vividly displayed. My hero faces all directions, that is farewell!

The farewell of the ancients can be described with deep meaning, because it is really not easy to bid farewell to the vast sea of people. Unlike modern people who can meet for hours, in ancient times, the information was not smooth, the horses and chariots were tired and walked slowly, so they cherished every farewell more, and maybe they never met each other in their lives.
