What is the legend about beginning of spring?

The legend in beginning of spring is that the year before in beginning of spring, when people were preparing to warmly welcome beginning of spring, unexpectedly the plague spread everywhere, making everyone infected with an indescribable disease. This disease is very strange. Looks like an alcoholic. Everyone is top-heavy and doesn't even have the strength to raise their hands.

The day before beginning of spring, a well-dressed man came to a village. He was very surprised to see that the village was so quiet that he couldn't hear the crowing of chickens and dogs, and no one was walking around. He came to a house near the village and knocked on the door. The Taoist priest called several times, but no one answered. Later he saw a middle-aged man and repeatedly asked what was going on. The middle-aged man raised his eyelids, closed his eyes and said intermittently in a weak voice, "Everyone in the village has my disease."

Continuing custom: After the plague was solved, people lived a quiet and happy life. However, people will never forget the Taoist priest, not to mention the radish that saved them from suffering. Since then, the villagers will eat some radishes at the beginning of spring to pray for peace. The custom of eating spring came into being and continues to this day.
