Not YT channels with an interracial couple with 混血儿kids. Eurasian 混血儿youtubers.
The only ones I know J Lou, Megan Jacques, Asha Cuthbert, Jasmine Lipska, Hannah Vanharanta, Christina 靠右邊走 and 金魚腦Goldfish Brain.
I also know 混血 male youtubers like Toto 郭头头 and Gordon Lau (who’s half African, half Cantonese) and maybe others I can’t name at the top of my head
If anyone knows any others, please let me know!
