To elaborate, they go to some awesome wall sections (that have never been discussed here), have guides who are capable of physically carrying you down if you get injured, and attract cool customers.

That having been said, the maps/instructions on their website are easy to replicate on your own. Just be prepared to pay off the gatekeepers, and haul your injured companion off of the mountain if need be. In addition to saving money, going on your own will spare you of the need to head out at 7a. Please join our Wechat group if you go alone; 100 people are there to help you.
