Why is the overseas theater Huang Shoupa named Huang Shoupa?

Huang Shoupa originated from a touching American story. A man who spent four years in new york prison wrote two letters to his wife. In the first letter, he wrote to make her forget him. Three and a half years later, when the prison decided to release him conditionally, he wrote her a second letter. The letter said that if his wife forgives him and is willing to accept him, she will tie a Huang Shoupa on the old oak tree at the entrance to the village. When he got home, he saw yellow handkerchiefs hanging on the oak tree, fluttering in the wind like flags, welcoming him back.
