Sequel 184: Harem WeChat Groups

After helping an elderly lady put on a modified short mamian skirt, Bai Hui hurried over.

She had the feeling everyone was taking part in some collective activity, and Bai Hui wanted to actively fit in so she would not feel excluded for lacking the same unspoken understanding as everyone else whenever the topic came up.

Girls were especially sensitive to this sort of thing. They wanted to fit into all kinds of circles and were also keen on actively building circles centered around themselves—or at least ones where they held a relatively important position.

That was one reason a girls' dormitory could create so many WeChat groups.

So here was the question: with Shangguan Dandan, Bai Hui, Liu Yuewang, Zhong Qing, Zhou Shuling, and Zhu Juntang present, could elementary school student Zhou Dongdong calculate how many WeChat groups they could create in total?

The process was simple, but it still exceeded Zhou Dongdong's capabilities. After all, plenty of college students and college graduates could not calculate it either! All they could say was: "Say that again and I'll curse you!"

Zhou Dongdong could randomly join one of the groups, so how many more WeChat groups could be created because of her presence and participation?

An Nuan joining would make the group dynamics even more complicated, so the final answer was that problems between women had no solution.
