1: Fan Bingbing (33) is quite younger than Li Bingbing (41). Or maybe: Fei Fei Sun (25) or Yifei Liu (27) if you mean much younger, please add an age
2: Euroasians are harder to find, especially 'young' ones (also here NO age specification from your side). So I just put some euroasian ladies together: Chloe Bennet, Hailee Steinfeld, Malese Jow, Vanessa Hudgens, Katie Findley, Shay Mitchell, Kelsey Chow, Nicole Gale Anderson, Lulu Antariksa, Anna Maria Perez de Tagle, Cinta Laura Kiehl
But I think Daria Sidorchuk would fit better in the role. Though she's not Euroasian.
3: Daria Sidorchuk as above. Cintia Dicker, Barbara Meier, Jane Levy
