Desire for a pure land, the road is crowded. Wushi Town, a stone village built of volcanic rocks, the setting sun is falling, the small villages are surrounded by terraces and mountains, and the warmth is like a new life. Back on the road, the sunset falls at the end of the road, and the Heart of Gold is played in a loop. A song from the 90s, the Johnny Cash version has a favorite playlist for a few years. Wherever you go, where you stop, you have to Keep searching for a heart of gold.
