Not a potholer myself, I'm not up on the technical terminolgy. Is 天坑 a sinkhole, or is there some other technical term?

It's just 'Tiankeng', perhaps because this large karst topography exists mainly in China.


See in wikipedia.

  • Thanks! I bet not many people would know what that is if I used the word! Also, it might be fun to hear how non-Chinese say it!

  • @Gangosa It seems that some famous Tiankeng have been named with sinkhole, such as Minyé Sinkhole and Crveno Jezero Sinkhole. haha, maybe everyone just says the pinyin when says it.

@Gangosa In gaming community among Chineses, 天坑 also means low-skilled players and trolls. It's just another interesting fact.

  • Well as far as poker or chess are concerned, 我是天坑的!

  • @Gangosa plus one more. 坑 can describe a project that is paused for a long time or that has not ended so far. To start a project is 挖坑 and to carry it on is 填坑. A big one is 天坑. A typical case is A song of ice and fire. 马丁挖了一个天坑,希望他在有生之年能把坑填上。George R.R. Martin dug a 天坑, I wish he can fill this 坑 before his last day.

  • Cool, thanks, I'll try to remember that, but I have enough trouble trying to remember normal Chinese!
