Guizhou discovered the underground Great Wall of 970 kilometers, see what the layout is like 

是的 很多人不敢

谢谢提醒

水力，LED耗電小

贵州最不缺的就是电

这个倒是没有仔细看

怎麼可能一個人?誰幫他拍的那麼全面?呵呵呵!

整個景區都沒有見到其他遊客,試問如何維持下去？各有興趣的要早些去見識一下了。

请 澄清 证明

希望中國政府把全部里程继续修理好，古为今用 必須要能为人民大众所備用 世界所有人的关心

那就迷路了😄

In ancient times, it depends on when the emperor was. It may have been after the Tang Dynasty. Cinnabar actually has a great effect, and the anti-corrosion you mentioned is also part of the effect.

@@xingjilvtu Yes, you have taught me about the Chinese dating system from the year of reign of the emperor when you have read stele to us. Thank you my good teacher. It just takes a long time for my aging brain to retain new information. On the other hand there's quite a lot of information in there - but sadly not about China. I joke that my brain is running out of disc space! which feels better than admitting I'm getting old.😂 Tonight I discovered cinnabar (Mercury sulphide HgS) is the pigment used for carved red lacquer ware, possibly as early as the late Song dynasty - so beautiful. I also discovered that by combining it with lacquer, the Chinese prevented it from emitting poisonous mercury vapour at room temperature. Yet another win for ancient China 👍 Another point from the video. I was also puzzled by how a metallic ore, cinnabar, had formed veins in a sedimentary rock - limestone (You showed us the bedding planes very clearly). There were no signs of great heat from magma changing the limestone to marble. Apparently cinnabar does not come from magma, but from alkaline hot springs. I'll be able to ask a young hydrologist at Christmas (family time like your new year)

Err.. territory of ancient China before Qin dynasty only covered what are today northern part of China, southern half of China that was incorporated later were also termed as East Asia, not South East Asia.

請澄清反應

是所有礦洞的總長度。裏面蜿蜒曲折，歷朝歷代挖了非常多礦洞。

还好 现在景区还是比较完善

你知道一米几高的人体里可以有7-10米的肠子吗？

敝路襤縷😅……。

繞山繞來繞去光貴州里繞一萬公裏也能啊，距離不是只有直線

肯定不是直线距离。山里挖矿道肯定是弯弯曲曲上上下下的。就好像相邻的两座山头直线距离可能很近可以直接对歌，但是如果要修山路连接交通，可能就得修个几十上百公里。这里肯定说的是挖出的矿道本身的长度。

古代時期沒有現代先進的器具，如果單是用人工開鑿苦挖完成那是根本不可能的任務，但願考古學家前往研究把答案找來～

五一不敢出去

人类真的什么都不放过，现在明白为什么会地裂，人类为大地付出什么？

Nice place...good job...brother...👍🇲🇨❤️🙏🙏🙏

一米多的人肚子里面的肠子有7-10米。 这个隧道弯弯曲曲的几百公里有可能

铜仁

不会！矿洞里开采的是朱砂，不是水银。

Turn off CC 😂就不會重複！

好幾條誰跟你一條970公里

看來中國人不全是好騙的白痴
