Thank you for your detailed research, this is such an educational post! I think the (Michael) Jackson family is another well-documented music family, and the Korean-born Americans the Kim Sisters are another interesting case study.

What do you think, in summary, are the main contributions of family? From reading your post, it seems like 1) Training in music/showmanship, 2) Financial support, 3) Managerial support, 4) Emotional support, and/or 5) Discipline/perseverance.

Really appreciate your bilingual work as well, it's a big inspriation for my English/Chinese blog :)
