Roots was the Luobu and Zibu of the thirty-seventh department of Dongcong Wuman in Tang Dynasty. In the Yuan Dynasty, Roots County was established in two parts. 1960 was withdrawn from the county and merged into Lufeng County, Chuxiong Prefecture. During the reign of Emperor Xuanzong of the Great Tang Dynasty, the emerging Nanzhao Kingdom rose on the shore of Erhai Lake. Its territory extends northward to the Dadu River, with all of Yunnan, southern Sichuan and western Guizhou. Its political and military influence spread throughout Indochina Peninsula. In such a vast country, almost every generation of Nanzhao princesses came from Roots. It is said that they are all beautiful women, and history has left us the story of "the city of beautiful women". In the Republic of China 10 (192 1), Chairman Li wrote "The Peak Height of Tianmu" and a piece of it were sent to Beichang Village, Luoci, to celebrate Liu's centenary birthday, and the centenary memorial hall was specially approved to show his virtue. This is a great honor for a mountaineer on the border, but it is not the first time in Roots. 10 years ago, when the Qing Dynasty was about to perish, I still did not forget to build a "Zhenshou Square" for Sok Li, the king of Shangluo Village, when Li 109 years old. "Longevity" is in Roots and Old Town of Lijiang, Yunnan, which is still in the ancient streets, ancient temples and famous temples. Those gray tiles and red walls, deep curtilage compound, dilapidated and blackened carved beams and painted buildings are exposed from the crack of the door, ringing bells and shouts of horse drivers echo in the narrow streets, and the nameless wild flowers blooming on the roof of the eaves in the sunset, gray and yellow desolation, are so out of place under the blue sky, in the middle of the green earth all over the mountains and plains. I don't know whether Roots is the past or the reality. A place name that does not exist, a place that exists, was once a "beauty", once a centenarian between heaven and earth, and finally disappeared into the vast history books. This is roots' past. "The shipwreck crosses Qian Fan", a new blue town was born here.
