The Shenhe and Yun Jin banner, as well as the Ganyu, Xiao, and Zhongli rerun banners, appeared during the Genshin Impact 2.4 stream.

Yun Jin's name has popped up several times already in Genshin Impact. Back in January 2021, dataminer Lumie shared a render of the character on Twitter.

As you can see at around the 2:44:10 mark in the clip from last night's industry awards show below, Mihoyo has offered the first glimpse of upcoming character Yun Jin in action - well, sort of.
