PROGRAMMING:Taoist priest, how do you want to die
Story: [he came to me in white with an umbrella. He said he would take me home. And I had already fallen into his deep eyes, a throb in my heart. He pulled me under the umbrella. I learned that he was a Taoist on the mountain and just went down to collect herbs. He gave me his umbrella. I went back alone and watched him at the door of the hut.
Later, I bought a box of sweet scented osmanthus cake by collecting herbs and selling money. I went to the mountain to thank him, and he accepted it happily. I walked on the mountain road with him, playing like a child, and he sent me down the mountain.
After that, I always give him something, whether it's made or bought by myself, he will accept it happily, and then we chat. Every time he sent me down the mountain, we rode together and played together. I remember when I gave him harness, he was very happy. He leaned over my ear and said that he would always protect me.
It rained suddenly and my hut was in tatters. So I decided to be a Taoist in the mountain, so that I could accompany him forever. I took the umbrella he gave me, and a few of my family property to go up the mountain to become a Taoist. But he doesn't seem to be here. Another Taoist priest asked me again and again if I was sure that I would become a Taoist. After becoming a Taoist, I would break the world of mortals, even if I could stay with him forever. So he changed into a plain dress and became a Taoist.
After that, I met him every day. He was the same as before, always playing with me, but I always found that he always went down the mountain more and more frequently. But every time I come back, I will bring rouge and red makeup for me. I'm so happy. That night, he just came back from the foot of the mountain, knocked on my door, to give me a rouge, said that this is the latest model, the girl used after particularly beautiful. I am very happy, said to him, this seems not very good, always give me things. It's not good to be seen by others. He said just keep it. He asked me what it was like to miss someone. Before I could answer, he turned and left. My heart was throbbing.
After three years in this way, he suddenly said that he wanted to return to secular life, because he had a private life with a girl who sold Rouge in the countryside. And promised to marry her, so the Taoist priest took everyone's blessing and went down the mountain. I stupefied Leng in situ, eyes gradually moist. It turns out that he didn't like me three years ago. The rouge he gave me was just to please her. Naturally, the person he missed was not me. Thinking of this, I can no longer hold back tears.
Soon came the news of the Taoist wedding banquet. I pretended to catch up with them by chance. When he saw me, he was stunned. He was still dressed as white as ever, and the beautiful woman beside him had a flowery face.
She asked him who I was. He said that I was a Taoist friend when I was a Taoist in the mountains. Some of the beauties around show a sweet smile, and I don't know why I think they are a good match.
But I still want to ask him whether the harness I sent is not good enough, whether the sweet scented osmanthus cake I didn't cover the heat that day, whether people in the world are like this, even their promises can be taken back at will.
I want to hug him and leave a lip mark on his white side face, which makes others surprised, but I can't. Can only forbear to smile to give them blessing. And gave them the umbrella that Taoist priest gave me as a gift. I drink alone in the corner, turned away, no one saw my tears after turning.
Later, I went to many places by myself, from spring to winter. At that time, it was like a dream I had. Now I wake up. There's nothing left
After singing a cool song, she was ready to jump off the cliff. When she got to the foot of the mountain, she found that there were n steps in front of her. Due to the limitation of leg length, she could walk three steps at most each time, so she could walk to the n-th step in different ways (when n = 1, she could only walk one step, so there was one way to get to the first step. When n = 2, she could walk two steps, one step at a time, There are two ways to get to the second step. The kind-hearted Chen Mou Shuai couldn't bear her to die like this, so he borrowed the "super invincible spiral transposer" from the "eight level gale" doctor and prepared to exchange her position with the Taoist priest when she jumped off the cliff. So, schoolboys and schoolgirls, can you figure out how many kinds of death methods there are for Taoist priest Zha Nan?
