What does "twice" mean in a football match?

A double goal means that the same person scored two goals.

Dichotomy is an old saying, which means doing the same thing twice.

During the reign of Su Zong in the Tang Dynasty, there was a beautiful woman named Chen Xingyuan. One day, her plum blossom suddenly withered. On the same day, Mei Liangyu, a gifted scholar who was harmed by treacherous court officials, came to her house to make a living as a buddhist nun. Later, they fell in love. Soon the northland invaded the south, and the king of Tang couldn't resist it, so he sent Chen Xingyuan to appease it. Chen Xingyuan jumped off the cliff reluctantly on his way to Fanbang. Legend has it that he was saved by the ghost of Wang Zhaojun and sent back to the Chen family. Finally, Chen Xingyuan and Mei Liangyu got married, which touched Chen Jiamei's tree and reopened that day, hence the idiom "plum blossoms twice".
