Why is everyone related 😂😂😂

I think it's because of the way families marry other rich families so it'll make sense how everyone is somewhat related

believe me, if you're a part of wealthy chinese fam, everyone is related

I think in this scenario, Bai just meant it as a greeting, cause there is no one in the He family that Bai is related to, I think it’s a tradition or a thing in Chinese culture to call some one an aunt or an uncle if your families are very close friends. And since both Bai’s and the He’s are prominent families they must be close friends, and I think this is why they used this type a greeting.(▰˘◡˘▰)
