How often does the strange treasure chest refresh?

Genshin Impact's treasure chest is updated every day.

The opening progress of the strange treasure chest is related to the progress of the foggy sea series of world missions. It opens every day and is divided into three stages. You need to complete the main tasks of the day before you can enter the next stage. Because of its unique refreshing mechanism, some treasure chests will knock the original stone of the normal treasure chest to its original position. I suggest you touch the treasure chest on the map as soon as possible to avoid being knocked off.

The number of odd-feed treasure boxes

In the original god game, there are 46 strange treasure chests, and 43 strange treasure chests are located in Guam. Players need to dispel the fog on River Guam in order to get the strange treasure chest on River Guam normally. If they can't find the treasure chest, they can clear the ordinary treasure chest around them and have it the next day.
