Genshin Impact: How To Open The Locked Gate in Chizhang Wall

There is one huge (not really) ruin right in the center of the Chizhang Wall. To get inside it, you need to get Fragrant Woods from 2 cauldrons via the descriptions from the Diffuser Inscription in front of the gate. After completing the puzzle, you will get a Luxurious Chest and 2 Common Chests inside the ruin (along the way, there are 2 Precious Chests). There's also one Spirit Carp inside here.

Just a note: In the game, these items are just called 'collapsed ancient ruins.' It might cause confusion so I'm just gonna call it pillars in my guide.

...Present the jade at dawn, and glorious halls at dusk; The pleased spirits descend, with fortune and blessings eternal...

...Scent of orchids, fragrance of flower, the jade cauldron and golden goblets; the fragrance wafting towards the east, burning incense towards the west...

...Build an altar for sacrifice, sweet wine libation and imbibation; shining brightly for thousand of years, illuminating all directions...

Let's ignore the mumbo jumbo and go straight to the puzzle. To solve it, you need to go to 2 locations and solve a ruin/pillar puzzle (move collapsed ancient ruins - or pillars - to the correct position). The 2 locations are marked in the image above.

The West Cauldron

In this location, there will be multiple Ruin enemies. The focus here is the Ruin Hunter right on top of a locked gate. Interact with it to activate and defeat it.

The gate will automatically be opened and inside the locked gate is a small-sized ancient pillar. Place this short pillar in the middle part of the stairs leading to the cauldron.

Just behind that short pillar is a big-sized ancient pillar inside a puddle of water. Pick it up (the water level will decrease and you can get the key to unlock the gate beside you for a Spirit Carp) and place the big pillar at the back of the cauldron.

For the last ancient pillar, go down the stairs at the south and you should be a Time Trial Challenge just beside the stairs. Behind that challenge is a small locked area with the last middle-sized ancient pillar in it. There's no key for this one because you don't need it. Just go around the locked gate and there will be a busted wall where you can just walk in and get the last pillar (the gate will automatically be opened when you pick up the pillar).

Place the last pillar at the last slot, at the foot of the stairs leading to the cauldron. The chest will be unlocked and you can pick up the shiny item for the Fragrant Wood.

The East Cauldron

This one is a bit more complicated (but actually easy) than the previous cauldron but just follow me. First of all, defeat all the Treasure Hoarders loitering around so they won't bother you.

Then, in the middle of this ruin is a short ancient pillar (gonna name this pillar #1 or you might get confused afterward). Pick up and place this pillar #1 just on the tile beside it.

This will unlock the gate in front of you. Inside the gate is another ancient pillar but a tall one (gonna name this pillar #2)

Pick up pillar #2 and place it on the tile opposite of the pillar you just found it in (There should be another pillar of the same size beside the tile).

Then, pick up pillar #1 and place it on a tile in front of pillar #2. Same as before, there should be another pillar of the same short size just beside the tile.

With this, another gate should open with the last ancient pillar with the biggest size (gonna name it pillar #3).

Pick up pillar #3 and place it on the last tile of the stairs that lead to the cauldron. BUT, make sure your back faces the cauldron when placing pillar #3 so it will form a gate just like in the image above.

Pick up pillar #2 and place it on the middle tile of the stairs that lead to the cauldron.

Lastly, pick up pillar #1 and place it at the top of the stairs that lead to the cauldron. Get the Fragrant Wood and Precious Chest, and go back to Chizang Wall for the Diffuser.

Give the 2 Fragrant Woods to the Diffuser and the gate leading to the ruin will be unlocked. Inside it, you need to defeat a Ruin Grader first before you can get the Luxurious Chest.

The 2 Jade Fragments

But it's not over yet! Once you open the gate, you will see a huge Ancient Jade Pendant in there. Go to the 2 locations above to get Jade Fragment (Right) and (Left).

Go back to the ruin in Chizhang Wall and interact with the Jade Pendant again to give the 2 fragments. Press T if you're on PC to be teleported to a hidden area with the last mural.

Clean the mural and you will get an achievement called The Mural Veil. After waiting for another few seconds, a Luxurious Chest will spawn and you will get another achievement named A Ruined Tale.
