What is the origin of "there is no Amitabha in the South"?

The so-called "there is no Amitabha in the south" is an expression of the way of pure land Sect chanting Buddha. "Amitabha Namo" is a transliteration of the Sanskrit name Amitabha Namo. "Nanwu", also translated as "Mimo" and "Namo", means "paying tribute" and "coming back to life". Amitabha, the founder of Buddhism "Western Elysium", is also the main object of worship of Pure Land Sect in China. The sentence "There is no Amitabha in South China" means "To Amitabha" and "Return Amitabha".

The pure land Sect of Mahayana Buddhism believes that there are countless buddhas in the infinite universe, so there are countless "pure lands" where the buddhas live. Among them, the place where Amitabha lives is called "Amitabha Western Pure Land", also called "Western Elysium". The so-called Amitabha Buddha is said to be the leader of the "western paradise", so it is also called "receiving Buddha" because it can attract Buddhist practitioners to the west. "Amitabha" includes "Infinite Life Buddha", "Infinite Light Buddha", "Infinite Light Buddha", "Unscrupulous Light Buddha", "Flame King Light Buddha", "Pure Light Buddha", "Happy Light Buddha", "Wisdom Light Buddha", "Constant Light Buddha" and "Difficult Thinking" according to the Infinite Life Sutra. He made 48 kinds of big wishes in front of the "Buddha of Freedom", vowing that if he realized becoming a Buddha, he must save all sentient beings to his pure land and paradise. After Fazang made a vow, he practiced diligently and finally gained the Tao. The Buddhist country he took was called "Anle". Because it is located in the west, it is generally called "Western Paradise". This is the origin of what Buddhism calls "the western paradise".
