A Genshin Impact enthusiast has published several photos. It is claimed that this is how miHoYo's (HoYoverse) game is promoted in Vietnam.
The photos by hoatongoc show several official Hoyo Fest artworks: the creators of Genshin Impact commissioned artists to create them.
The choice of locations is remarkable: in one of the photos, barbed wire looms above Genshin Impact, while one of the colorful artworks was placed on a rather rundown building.
