Hi, Cannot come
.
呢條石河 at (& close to) 南天門石澗尾, difficulty- I think '6 stars'. The cliff is very vertical ga. Also, take care- 落石. fall back to 南天門 石澗 (so take care the falling stone as the falling stone will fall to 南天門石澗 and causing danger to other people (other than your team)). Take care this point.
Also, don't go alone ar. Danger ga.
Ha Ha. Bye.
