Door to Khaenri'ah location in Genshin Impact: Hidden achievement and references

sportskeeda.com:

The Gate of Zulqarnain is often seen as a Door to Khaenri'ah in Genshin Impact. However, some players have no idea how to reach this area or what it's used for in Version 3.6. If you go near the Viewpoint in this location, you will receive an achievement titled "...Abandon All Hope, Ye Who Enter Here." That name is obviously a reference to Dante Alighieri's Inferno, the first part of his iconic Divine Comedy.

This achievement is worth five Primogems in Genshin Impact. Players cannot currently open the doors to reach Khaenri'ah. Travelers who wish to access this interesting location must complete the Khvarena of Good and Evil World Quest series up to the point where they can access the final elevator to reach the underground area.

The Khvarena of Good and Evil series includes the following quests that Genshin Impact players must do:

There are plenty of Primogems and other minor rewards to unlock along the way, so it's not as if Travelers are only doing this for a single hidden achievement. Once you've beaten these quests, use the Teleport Waypoint that's underground in Tunigi Hollow. Head down the elevator that is southeast of that Teleport Waypoint.

Keep going down and activate the nearby switch to open the eastern door. Go through the east path until you finally see a Viewpoint you can approach.

Genshin Impact players should eventually be at Hangeh Afrasiyab. Keep going east until you get very close to the Viewpoint to unlock the hidden achievement, "...Abandon All Hope, Ye Who Enter Here." There is also a Luxury Chest hidden near the Door to Khaenri'ah.
