Copper Whistle

A bronze whistle, fifteen years of waiting. When I was five years old, my fourth brother was expelled from the palace and gave me a copper whistle: "Blow it if you miss me. No matter how far away I will be, I will come back." I didn't blow it, I didn't dare to blow it. I'm afraid he won't come back. Fifteen years later, when the barbarians destroyed the city and the mountains and rivers were shattered, I finally blew the whistle. The whistle sounded across the mountains and thousands of miles away, someone turned around and said: "Fifth brother, I'm here." This time, it's me who goes to find him.
