Jiang Fan tank and samantha is right.
She was known as Xiaoqiumei on Douyin and had over 100,000 followers.
And it turns out she's wise.
It seems very unlikely Xiao would be the first banner in the 1.
According to their statement, she had missed a step and fell.
The only point you mentioned that I think it could potentially speaking make sense is that Ningguang and Zhongli are related story wise so there wouldn't be anything weird having the same elements in the banner, but yes this doesn't seem very likely from a banner standpoint.
