"Sansheng" is a Buddhist language, which refers to past life, present life and afterlife. There is a legend of Sansheng Stone in Buddhism. It is said that Sanshengshi can reflect people's past lives. In real life, there is also a famous Sansheng Stone, which is located on the bank of the West Lake, at the east foot of Lotus Peak connected with Feilai Peak. It is about 10 meter high and exquisite. It is engraved with three bowls of Sansheng stone seal script and the inscription of Sansheng stone trace of Tang Yuanze monk. The inscription describes the origin of this sansheng stone and tells a touching friendship. In the Tang Dynasty, monks Yuan Ze and Ethan were good friends, and they agreed to go to Mount Emei to worship Buddha. He advocated taking Xiegu Road from Chang 'an to Shu, and Li Yuan advocated taking waterway from Jingzhou to see the panoramic view of the Three Gorges. Wheel ze ao however Ethan, so they walked hand in hand at the water's edge. When I arrived in Nanpu this day, I saw a woman carrying a baby to draw water in the river. Yuan Ze said to Ethan with tears, "It is for this reason that I don't want to go this way. I have long predicted that this woman's reincarnated baby will not escape today! Come back in three days, and I will use a smile as a voucher to meet you outside the Qiantang Tianzhu Temple in twelve years. " With these words, Yuan Ze passed away. Three days later, Ethan came to this house and saw the woman's child. The baby really smiled at him. Twelve years later, Li Yuan went to Tianzhu Temple in Hangzhou according to the appointment. Under the moonlight of Mid-Autumn Festival, I heard a shepherd boy blowing a trumpet and singing: "Old ghost on Sansheng Stone, don't talk about enjoying the moon and singing the wind. Shy lovers come from afar, although the opposite sex always exists. " Knowing that this was Yuan Ze, Ethan quickly stepped forward and asked, "Are you all right?" The shepherd boy replied, "Gong Li is a true believer! I'm not like you, so don't come near you. I only encourage you with diligence. " After that, he sang another song: "There is nothing in front of me, and it will break my heart to say it." Wuyue searched all over the mountains and rivers and wanted to go back to Qutang. "After singing, I walked away. Last life, this life, next life, are very lucky. The so-called "three lucky students" is of course a metaphor for extreme luck. This language comes from the ancient children's enlightenment reading "Study in Qionglin": "There are thousands of strange things, and it is said that three students are lucky. Yunfu said that one day, Lang Xianping, who worked in North Korea, went to the temple and had a dream. He dreamed that he was in front of an old monk with blue eyes and only saw a wick incense burning in front of him. Although the smoke flame was weak, it never went out. The old monk said to the provincial lang, "This is the incense you wished for. The smoke is still there. You have experienced three lives. In the last life, Emperor Xuanzong of Tang Dynasty was the inspector of Jiannan appeasement, in the next life, Emperor Xianzong was the minister of West Shu, and the next life is today. "Provincial lang suddenly woke up. Today, "it's an honor to meet you" has become a polite expression, such as "it's an honor to meet you. "
