A man accidentally traveled back in time to the 1960s. He was penniless and his family was struggling to make ends meet. Fortunately, he had a golden finger on the compass and could predict misfortunes and fortunes and look for opportunities every day. Relying on the guidance of the compass, his home was filled with the smell of meat every day, he was completely free from hunger and cold, and he even married the village girl he longed for. When his uncle was seriously ill, he relied on the compass to find a good prescription to save his loved ones. He also relied on his guidance to find a stable job for his family. From then on, the family turned around and their lives became more and more prosperous.
