Legends of laurel

Once Apollo saw Cupid, the little god of love, playing with a bow and arrow. He warned Cupid impolitely, "Hello!" Bows and arrows are very dangerous things. Children should not play with them casually. " It turned out that Cupid, the little god of love, had two very special arrows: those who were shot by him with that sharp arrow made of gold would immediately be passionate about love, and those who were shot by another blunt arrow made of lead would hate love very much.

Cupid was not convinced by what Apollo said. When Apollo wasn't looking, he shot the arrow of love at Apollo with a whoosh, and Apollo immediately lit a flame of love in his heart. Coincidentally, a beautiful girl named Daphne came. The naughty Cupid shot the blunt lead arrow at Daphne, and Daphne, who was shot, immediately became very disgusted with love.

At this time, Apollo, who was shot by the arrow of love, was deeply in love with Daphne, so he immediately expressed his admiration for Daphne. But Daphne said angrily, "go away!" I hate love! Stay away from me! " He galloped into the valley like an antelope. But Apollo was not discouraged by the pursuit of Daphne. He took the harp and played a beautiful tune. No matter who hears the sound of Apollo, he can't help but come up to him and listen to him play.

Daphne, who was hiding in the mountains, also heard the beautiful sound of the piano and was unwittingly intoxicated. "where did you get such a moving sound? I want to see who is playing. " With that, Daphne had already been fascinated by the sound of the piano and went to Apollo. Apollo, who was hiding behind a boulder and playing the harp, immediately jumped out and came forward to hug Daphne. Daphne ran when she saw Apollo.

Apollo chased after him and shouted, "I am not your enemy, nor am I a ferocious beast, let alone an unreasonable man. why are you avoiding me?" Although Apollo kept shouting at Daphne, Daphne did not hear it and continued to run forward. But no matter how fast Daphne ran, she couldn't run Apollo.

After running for a long time, Daphne was exhausted and out of breath. At last she fell to the ground, and seeing that Apollo was about to catch up, Daphne cried out anxiously, "help!" Help! " At this time, the river god heard Daphne's cry for help and immediately used his magic power to turn her into a laurel tree. Daphne's hair turned into leaves, her wrists into branches, her legs into trunks, her feet and toes into roots, deep into the earth.

Apollo saw a great deal of remorse, he was very sad to hold the laurel crying, but the laurel kept shaking. Although Daphne had become a laurel, Apollo still loved her. Apollo stared at the laurel and said fondly, "although you have not been my wife, I will love you forever."

I will make my crown of your branches and leaves, my harp of your wood, and adorn my bow with your flowers. At the same time, I want to give you forever young, not old. " Daphne, who had become a laurel, was deeply moved and nodded her thanks again and again. Perhaps blessed by Apollo, the laurel is evergreen all the year round and is a very popular plant.
