What does the warmth of Lantian mean?

The sun-dried jade from the blue field makes the smoke rise.

Description: Meiyu is produced in Lantian Mountain. Where there is jade, it is hazy, but people only see the smoke in the mountain and don't know where the jade is. Beautiful jade is like a pearl in the sea, and no one appreciates it.

Lantian Mountain is a famous jade-producing place in the southeast of Lantian, Shaanxi Province. This mountain is sunny and contains jade gas (the ancients thought that treasures have phosgene invisible to ordinary eyes), and Ran Ran rises. However, although the essence of Meiyu is far away, it is not close, so it is out of reach, representing an extremely beautiful ideal scenery, but it is impossible to grasp and approach.
