What is the story about the origin of peony in Luoyang, Henan?

Luoyang is the "ancient capital of thirteen dynasties", with Xia, Shang, Western Zhou, Eastern Zhou and Eastern Han dynasties 13, and it is the first batch of historical and cultural cities and famous ancient capitals in the State Council. Luoyang is adjacent to Songshan Mountain in the east, Qinling Mountain in the west, Yi Que in the south and Mangshan Mountain in the north. Since ancient times, it has been known as "the hinterland of Kyushu, the thoroughfare of ten provinces, the defense of rivers and mountains, and the situation is the best in the world". Luoyang's unique geographical location provides good natural conditions for the vigorous growth of peony, so it is known as "the most suitable flower in Luoyang, and peony is especially strange". Peony is one of the earliest ornamental flowers in our garden. At the beginning of the evolution of peony cultivation, it formed an indissoluble bond with Luoyang. Luoyang peony began in Sui Dynasty and flourished in Tang Dynasty, while "the best in the world" was in Song Dynasty, with a history of 1500 years. In this long historical process, Luoyang peony is not only famous for its elegance and national color; With its natural love, the world is king and always leads the group. Luoyang has also become a sacred place for peonies in people's minds. The cultivation of Luoyang peony began in Sui Dynasty. Emperor Yang Di (605-618) said, "200 Ali Zhou is Xiyuan ... Yizhou enters 20 boxes of peony" and described the name of peony varieties. Song Gaocheng is also called "Peony was handed down by Emperor Yang Di". It can be seen that Luoyang is one of the earliest peony cultivation areas in China. In the Tang Dynasty, as the capital of Luoyang, peony was planted more widely, and the varieties of peony in Luoyang were richer, and professionals engaged in peony appeared. "Song is a single father, and he is good at planting peony. There are thousands of varieties of peony, and people don't know their skills. " At that time, peony had at least five colors: crimson, deep purple, pink, white and yellow, and a double petal variety appeared. After the Tang Dynasty, Zhuang Zong (923-926) once "built Fang Lin Temple in Luoyang, and planted more than a thousand peonies in front of it", which was no less than the Tang Palace in Chang 'an. In the Northern Song Dynasty, Luoyang peony was the best in China. Peony is the best in Luoyang. People in Luoyang don't call peonies by their first names, they call them flowers. Its slaughter is called the real peony in the world. ""in spring, there are no flowers in the city, even those who bear it; When the flowers bloom, the scholars will do it. " It can be seen that it has become a folk custom for peony people to raise peony and enjoy peony. At that time, the cultivation techniques of peony were generally improved. At the same time of sowing and propagation, peony is "bad without grafting" by grafting and fixed variation, which makes new varieties appear constantly. At that time, it came from Yao's family in Sima Po, Luoyang, and Wei Hua came from the family of Prime Minister Jin. Qian, a local resident of Luoyang, said, "People call the Peony King, and Yao Huang is the real king, and Wei Hua is the queen".
