The legend of pitaya is a tropical plant of cactus, which is native to Costa Rica, Guatemala, Barama, Ecuador, Cuba, Colombia and other places in Central America. It is not only famous for its longevity, tenacity and beauty, but also an excellent source of nutrition and beauty. According to local legends, the measuring ruler is a powerful symbol of nutrition. An Aztec legend describes in detail how powerful the measuring ruler is for women. When a poor Aztec woman got lost in the hot desert, she couldn't call for help, and the situation was very dangerous. She fell into despair, dying, and slowly entered another world in illusion ... The voice told her to eat the plants next to her quickly! Eat the plants around you! She struggled to stretch out her hand to touch it, but she couldn't open her eyes. She just imagined that there were scattered and stretched rulers around her. There are few other plants in this particularly hot desert. She saw flashing red light in the illusion, dotted with pitaya between the scales measured, like handfuls of burning hunting, and her beating heart was shouting, inspiring her to stick to it! A breeze, millions of young beauties came running to her with huge lilies! ..... In the dream, her hand touched a blow, and she felt groups of swaying fairies and clusters of brilliant flowers changing alternately in front of her eyes, like a thick green ruler. When she magically broke it, her hand was pricked with blood, but she didn't feel any pain. She seemed to be guided by a magical force, mechanically biting this thick ruler. The Aztec woman woke up, her physical strength recovered rapidly, and her almost chapped lips became magically rosy, gradually spreading all over her body like waves, and she walked out of the desert smoothly! The legend of this Aztec woman has been handed down from generation to generation. The measuring ruler is regarded as fairy grass, and pitaya is also called fairy fruit and honey fruit. No matter its branches, flowers, fruits and roots, it has become an indispensable special crop for local people and has unique medicinal and edible functions. As a sacred symbol, pitaya is respected by the world, and this tradition later spread all over the world with the invasion and expansion of European colonialism. Pitaya belongs to the upper class in the edible plant fruits of human beings, which implies many beautiful ideals of human beings, such as auspiciousness, health, wealth and longevity. Whether visiting relatives and friends or visiting patients, there must be a pitaya in the center of the fruit basket that people carry with them, which indicates many good wishes. No matter from national leaders to ordinary people, when offering sacrifices to ancestors, pitaya is often inseparable ... The origin of pitaya originated in the tropical rain forest area of Central America, belonging to the genera of fairy palm, ruler and snake whip. Pitaya has a deep historical origin with religious culture. Pitaya is planted near the Mayan and Inca pyramids in America and next to Vietnamese temples in Asia. Whenever there are sacrifices and major religious activities, they will sacrifice pitaya as a sacred fruit on the altar. What is even more surprising is that pitaya has an indissoluble bond with loong culture in the United States and Asia. The ancient Incas sacrificed pitaya with totems engraved with dragon images. This totem and pitaya both mean dragon in Inca. Even today, indigenous Mexican men like to call themselves China boys, which may be influenced by the legend that their ancestors came to the United States from China.
