Father's surname is Liu, mother's surname is Shen, and the names of boys and girls should be four words. . . .

Female: Liu Shen Liu Shen Mengdie Male: Liu Shen moved to Liu. Why do you have to add your mother's surname? Although it is respect and love for your mother, Liu Shen is really unhappy together. Although children will be laughed at when they grow up, they can ignore it, but maybe they will be dissatisfied with the name and even hate themselves. I'm just suggesting that it's best to just use Liu's surname.
