Can the yellow sand in the desert be regarded as a dragon in geomantic omen?

It's not easy to find a living Long Mai suitable for Yin acupoint, and we have to consider the problem and context of nozzle. There's a joke: Ten dragons and nine deaths, and Yi Long is at the tuyere (gas will disperse when it meets the wind, and it will stop when it meets the water, and things at the tuyere cannot be a shady place). So it's not easy to find a dragon, and it's even harder to find it, because it has to be buried in the dragon's head or mouth or something. If you just want to find a living Long Mai, it is very easy to find Long Mai. The so-called context depends on the ups and downs of the mountains. Even if the middle is broken (actually underground), the back will be connected, shaped like a crane knee. It depends on the feeling. Dragons are alive, dead, dull and fierce, so the ancients pay attention to gas. Mountains should not look dull, but lively. For example, a mountain range, like a sentence, is plain and unremarkable. It is better to bend a hook and grow many branches on the side (this is called having offspring and has a long history).
