English Original
During the Southern and Northern Dynasties (420-589), there lived a beautiful and intelligent princess named Lechang in the State of Chen. She and her husband, Xu Deyan, loved each other dearly. Fearing an invasion by the Sui Dynasty, they had a premonition that they might be separated during the coming chaos. As a symbol of their unity, they broke a bronze mirror in two, each keeping one half. They agreed to take their halves to the Lantern Festival fair on the 15th day of the first lunar month, hoping to reunite and join the mirror pieces together.
Their fears soon came true. Amidst the war, the princess lost touch with her husband and was taken as a mistress by the powerful minister Yang Su.
The following year at the Lantern Festival, Xu Deyan went to the fair with his half of the mirror. There, he saw a servant selling the other half. Recognizing it immediately, he inquired about his wife. Upon hearing of her plight, he was moved to tears. He wrote a poem on her half of the mirror:
"You left me with your broken mirror,
Now the mirror is back but not you.
I can no longer see your reflection,
Only the bright moon, not you."
The servant returned the inscribed mirror half to Princess Lechang. Reading the poem, she sobbed for days, knowing her husband was alive and missed her, yet believing they could never meet again.
Minister Yang Su discovered this exchange. Moved by their true love and realizing he could never win Lechang's heart, he sent for Xu Deyan and allowed the couple to reunite.
From this story comes the idiom "A broken mirror joined together," symbolizing the happy reunion of a separated couple.

南北朝时期（420-589年），陈国有一位美丽聪慧的乐昌公主。她与丈夫徐德言情深意重。他们预感隋朝军队即将入侵，国家将陷入混乱，两人可能在战乱中失散。作为夫妻一体的象征，他们将一面铜镜摔成两半，各执其一，并约定在正月十五元宵节时，带着半面镜子到市集上相寻，以期重聚，让破镜重圆。
不久，预感成真。战乱中，公主与丈夫失散，被权臣杨素掳去，成了他的妾室。
次年元宵节，徐德言带着半面镜子来到市集。恰巧遇见一个仆人在售卖镜子的另一半。他立刻认出，并向仆人打听妻子的下落。听闻妻子的悲惨遭遇，他不禁泪流满面。他在妻子的那半面镜子上题诗一首：
"镜与人俱去，镜归人不归。
无复嫦娥影，空留明月辉。"
仆人将题了诗的半面镜子带回给乐昌公主。公主见诗，连日哭泣不止，她知道丈夫还活着并且思念着她，却又以为此生再难相见。
杨素得知此事后，也被他们的真情所打动，明白自己无法得到乐昌的心，便派人召来徐德言，让这对夫妻得以团聚。
由此便产生了“破镜重圆”这个成语，用来比喻夫妻离散后重新团聚。
