Marriage is carved on the Sansheng Stone, and it is agreed in front of the Naihe Bridge for a hundred years. In fact, this sentence has the same meaning as the surface, but as long as the two words are explained, you can understand the three-life stone: "Three Lives" originates from the Buddhist theory of cause and effect and reincarnation. Buddhism believes that all living beings die here and there in the six paths due to their good and evil karma, in an endless cycle. The existence of sentient beings in the previous life is the previous life, the existence of the current life is the present life, and the existence of the next life is the next life, collectively referred to as the "three lives". The three lives of the Sansheng Stone represent "previous life", "this life" and "the next life" respectively. There are entanglements between this life and past lives! Many people's love starts from a feeling of déjà vu, and after falling in love, we will definitely look forward to the "destined relationship for three lifetimes". In a love that feels like déjà vu, I believe that the marriage in this life was actually destined in the previous life. Legend has it that people who have passed away will walk through Huangquan Road and when they reach Naihe Bridge, they will see the Sansheng Stone. The latter sentence can be explained by a nursery rhyme I remember. : "Lian Lian, you and I have agreed for a hundred years. If anyone dies at the age of ninety-seven, he will wait on the bridge for three years." Therefore, the meaning of the latter sentence is consistent with this sentence.
