Explanation
一箭双雕，是一个汉语成语，意思是射箭技术高超，一箭射中两只雕。后比喻做一件事达到两个目的。这个成语出自《北史·长孙晟传》，故事说北周武将长孙晟在护送公主出嫁突厥时，一箭射中两只雕，展现了他的高超箭术，也体现了做一件事可以达到多个目的。
One arrow, two eagles, is a Chinese idiom meaning to shoot two eagles with one arrow. Later, it was used as a metaphor for achieving two goals with one action. The idiom comes from the „History of the Northern Zhou Dynasty“ (北史·长孙晟传), which tells the story of the Northern Zhou general Changsun Sheng (长孙晟) who shot two eagles with one arrow while escorting the princess to her marriage to the Turks. This demonstrates his exceptional archery skills and the ability to achieve multiple goals with one action.
Origin Story
北周武将长孙晟，是一位足智多谋的将领。有一次，他奉命护送公主出嫁突厥。突厥国王摄图为了考验长孙晟的才智，便邀请他一起去打猎。在一次狩猎中，两只雕鹰正在争夺一块肉。长孙晟眼疾手快，一箭射出，正中两只雕鹰的胸膛，两只雕鹰应声坠地。这一箭射中两只雕鹰的壮举，不仅体现了长孙晟的高超箭术，更让突厥国王对他的智慧和胆识佩服不已。此后，长孙晟便以“一箭双雕”的典故，成为人们口中流传的“神箭手”，他的智慧和勇敢也成为了后人学习的榜样。
Changsun Sheng, a general of the Northern Zhou Dynasty, was known for his strategic intelligence. One day, he was ordered to escort the princess to her marriage to the Turks. The Turkic king Shetu wanted to test Changsun Sheng's intelligence and invited him on a hunting expedition. During the hunt, they saw two eagles fighting over a piece of meat. Changsun Sheng, quick and skillful, shot an arrow and hit both eagles in the chest at the same time. The eagles crashed to the ground. This feat, hitting two eagles with one arrow, not only showed Changsun Sheng's exceptional archery skills, but also impressed the Turkic king with his intelligence and courage. Since this event, Changsun Sheng became known as the „Double-Arrow Archer“ (一箭双雕) and his courage and intelligence became a model for future generations.
