Traveling to Mangya's Gaskule Lake and Blue Hole

From the Two Steps app, I found that there is a village called Dairsen near Gaskule Lake, so I decided to head there. Upon arrival, I discovered that Dairsen Village shares an entrance with a salt factory, and entry is only possible with an invitation from the village. Currently, Gaskule Lake has been unofficially incorporated into the Emerald Lake area, and all self-guided access routes (via Dairsen Village or the salt factory) have been blocked. Communication with security personnel is no longer an option. At the Emerald Lake ticket office, you can carpool for 50 yuan per person, with the total trip, including travel time, lasting about 1.5 to 2 hours. The advantage of going with them is that they know the exact direction and distance to fly to see the various large and small holes. The Blue Hole is a larger lake, but its colors appear dull and gray in the strong backlight of the evening. Morning might be a better time to view the Blue Hole.
