How to Unlock Hidden Palace of Zhou Formula in Genshin Impact?

In order to unlock the Hidden Palace of Zhou Formula in Genshin Impact, you need to discover and activate four flames “switches,” and then use your Geo on the appropriate pillar. The first step is to go to its location. You can find this particular hidden palace in the East of Qingce Village (where the Geo Statue puzzles are) and North of Wuwang Hill. You can see the exact location in the images below.

After reaching the location, you will have to kill enemies to make your life easier. Now, it is time to find the four flame-activated switches. The first flame is located next to the Geo switch and the second one is located on the ledge right above it.

The third one is on the cliff above the large stone block under which the palace is located. Lastly, there’s one across the pond from the first switch, but it’s behind a wind barrier. That’s not a huge problem, since you can climb onto the large rock next to it and hop inside the barrier. It will dispel when you light the fire. 

Once you have managed to activate all four fire switches, go to the large Geo switch (or pillar, if you will) and use a Geo move on it. Doing this will break the huge stone block and the Hidden Palace of Zhou will come from the ground. Notably, you will only be able to enter it if you have an Adventure Rank of 22 or more.
