Lantian jade has been reused in the Qin Dynasty. In "Journey to the West", Sun Wukong's "Waistful Lantian Belt" is described. The Lantian belt here is the "Jade Belt", reflecting that Lantianyu has become synonymous with jade at that time. Lantianyu's long history, profound cultural connotation and long-standing reputation fully demonstrate the status of Lantianyu's origin, and its historical name should be given effective legal protection.

In the long history of our country, the discovery, understanding, development and utilization of Lantianyu has a long history and endowed Lantianyu with profound cultural connotations. As far back as the Neolithic period more than 5,000 years ago, people began to use Lantian jade to make various stone tools, including jade and jade. This can be proved by the Neolithic artifacts unearthed from the Zhangzhang River in Lantian County. After entering the civilized era, Lantianyu was gradually developed and utilized extensively, and its reputation continued to expand. In the vast books, Lantianyu recorded and praised a lot. For example, Li Jizhen’s "Yuanhe County Map" contains "by Zhou Li. ", the beauty of the jade is smashing the ball, followed by the blue'. Covering the county with the beautiful jade, so the 曰 Lantian. A Tianshan in Lantianshan, a covered mountain, in the east of the county twenty-eight." Ban Gu’s "Xi Du Fu" contains "Lantian Meiyu". "Han Shu. Geography" contains "Lantian Mountain Out of Beauty". Zhang Heng’s "Xijing Fu" has the saying "Landian Zhenyu". Xin Yannian’s "Yu Lin Lang" has the famous sentence of "Lantian Lan on the head, Da Qinzhu behind the ear". "Han Han Shu. County System" also contains "Lantian out of the United States." "Han Han Shu. Wai Chuan Biography" said: "The wall belt is often the US gold cylinder, the letter Lantian wall." Tao Hongjing’s "Medical Doctors" said that "the jade is like a bean, and a blue field." Ruo Daoyuan's "Shui Jing Zhu" thinks that "the water is out of the Lantian Valley of Lantian County, and the so-called multi-jade is also." Sun Quanzheng in "Three Kingdoms. Zhuge Yu": "Lantian Shengmei is really not worthy." The poet Qian Qi used to make a jade pillow with Lantian jade. He once made a poem: "The water is rich, the water is precious, and the sorrow is sorrowful; there is no white scorpion, no snoring. Before the sun, a new ice is clear; Waiting for the autumn has arrived." Wei Yingwu's "Jade Jade" has the title of "Guangzhou levy Baiding, saying Caixi Lanxi. The night is homeless, deep in the rain", this "Blue Creek" is under the Lantian Mountain in Lantian County, "Blue Creek Jade" It refers to the "Lantian jade" distributed in the stream. In the "You Wuzhen Temple Poetry", Bai Juyi also used Lan Tianyu to express his feelings: "Dongyao is a strange stone, and it is accumulated in the sky. Wenyu is born outside. During the period, he died for a long time. Liangyu abandoned the donation; Or the time is fascinating, the night is connected with the star." Li He also profoundly mentioned Lantian jade in "The Old Man's Jade Songs": "The jade is jade and the jade is watery, and the scorpion is stunned. The old man is hungry and cold. Hey, the blue stream is not clear. "This "water" refers to the jewelry used by women. In the poem "Jin Se", Li Shangyin has the words "Yu Haiming Moon Pearl Tears, Lantian Day Warm Jade Smoke", "The Book of Poetry with the Polar Poetry" quoted Dai Shulun as saying: "The poet's scenery is like Lantian. , Liang Yu smoke, can not be placed before the eyebrows." Li Wei's "Tai Ping Yu Lan" also quoted the description of "Yu Yu Pei": Qin De Lan Tian Shui Cang Yu made jade, eight sides of the square button, Qin Xiang Li Si wrote, for Qin Shihuang made "accepted by the sky, both life Yongchang" The jade. ("螭 button" refers to the 螭 pattern on the jade or seal). It can be seen that Lantian jade has been reused in the Qin Dynasty. In "Journey to the West", Sun Wukong's "Waistful Lantian Belt" is described. The Lantian belt here is the "Jade Belt", reflecting that Lantianyu has become synonymous with jade at that time. Lantianyu's long history, profound cultural connotation and long-standing reputation fully demonstrate the status of Lantianyu's origin, and its historical name should be given effective legal protection.
