Emperor Qianlong was a charming man, a literati, and cherished Mengshan with profound historical and cultural accumulation. One day, Emperor Qianlong had a whim and took his entourage to the Wanghai Building, the main peak of Mengshan Mountain. Tired and thirsty, he took a break in Bei 'an under the leadership of his entourage. When the nuns in buddhist nun heard that the emperor was coming, they immediately lost their minds and didn't know how to receive them. Only a young nun named Yuan Zhen said, "Don't panic, you clean up and I'll take over." This Yuan Zhen was originally a good family. She has learned etiquette since she was a child, and from ancient times to the present, reciting poems is even more handy. It was only because of a strange disease that I became a nun.

At noon, Qianlong came to the mountain, hungry and thirsty. I was a little disgusted to see that there was only one nun making tea outside buddhist nun and no one came to pick her up. So I picked a stone and sat down. After a short rest, no one spoke. Gan Long suppressed his anger and accosted him: "Excuse me, Master, what is the name of this temple?" Yuan Zhen replied: "It is called buddhist nun, which means to ensure the unity and peace of the Qing Dynasty." Hearing this, Ganlong was happy. Seeing that the little nun was beautiful and clever, he really wanted to take the opportunity of Yuan Zhen's tea delivery to touch her delicate fingers. When Gan Longgang wanted to reach for tea, Yuan Zhen put the tea bowl on the stone table in front of Gan Long. Gan Long was very angry when he saw that Yuan Zhen was so ignorant of his interest, so he ordered Yuan Zhen to accompany him to climb the mountain. When Yuan Zhen was young, he often climbed mountains and was always ahead. Qianlong let Yuan Zhen pull himself up on the grounds that the cliff was too high to go up. Yuan Zhen said that the cliff was too high to reach, so he found a thin stick and asked Gan Long to grab the other end and pull him up. When Gan Long climbed to the top of the mountain, he shouted, "Liang Shanbo climbed the mountain and butterflies were flying." He wanted to take advantage of Yuan Zhen in the form of poetry, but Yuan Zhen said, "Here comes the midwife. Wow, it adds joy." Yuan Zhen means to compare Gan Long to a newborn. Gan Long was surprised and thought that this woman was not an idle person. She is not only beautiful, but also knowledgeable.

Later, Qianlong failed to achieve his goal from several aspects and sighed: "The dragon was beaten by shrimp in shallow water." Yuan Zhen immediately replied: "It is difficult to grow lice on your feet." When Qianlong heard this, he thought, What a clever woman! If you dare to tease the emperor, I will kill you if I catch the handle. I think I heard that this temple is called Jiu 'an, but this woman is called Yi 'an. Isn't this the crime of deceiving the monarch? Then he asked, "What did you call this buddhist nun? I have a bad memory and forgot. " Yuan Zhen calmly replied, "This buddhist nun used to be called an nunnery, but later he moved into eight nuns, and later he changed his name to Jiu 'an, meaning that the Qing Dynasty was always peaceful. "Qianlong admired Yuan Zhen, a girl with both talents and looks, and wrote the word" Nine Halls "for this purpose. This is the story of the famous "Qianlong Opera Yuan Zhen".
