Chen Yu (Yu) doesn’t know if it’s possible.
Actually, I think the father’s surname can also be Chen. In order to commemorate the mother, he can add love after the surname, or something else. This way Experience your child’s loving nature.
For example: Chen Ai (mother’s nickname or the last letter of mother’s name).
Finally, I wish you all the best to have a child. Cute, white and fat baby, a healthy and happy family.
