Wow! I clicked on the link. Amazing. Just the thought of them making it! And why would they go through so much work to do it? It must have had a meaning once. More than what's at the end now.
And I wonder how the tea house gets its supplies in tea and water - any tea plantations up there? A spring on top of the mountain? How do they heat the water - I suppose there won't be any electricity? If they do it the old fashioned way , i.e. a kettle on a fire, they also have to transport some kind of fuel up there...
And the idea of transporting any kind of stuff up there makes it even scarier!
