Twenty-one of their children, many they had through surrogates, were put in the custody of L.A. County Children and Family Services. Now, police continue to search for one of their nannies, who is accused of abusing a 2-month-old who belongs to the couple.
According to court documents, photos were taken on May 7 of a then-2-month-old boy who Arcadia police say had "an apparent head injury."
According to warrants filed by Arcadia PD, the boy's mother is Silvia Zhang.
Last Month, 7 On Your Side Investigates reported on how Zhang and her husband, Guojun Xuan, were arrested and then released.

But, 21 of their children, many of them living inside the Arcadia home and many of them born through surrogacy, were put in DCFS custody.
The couple is not facing charges, but police still want to arrest their nanny, Chunmei Li.
"It's suspected that she (Li) is responsible for some head injuries sustained by a 2-month-old that was living there at the house," said Sgt. Mario Castro with the Arcadia Police Department.
According to court documents, a security camera inside Zhang and Xuan's Arcadia home shows Li holding the then-2-month-old.
Arcadia police say footage they obtained shows Li "placing him down out of camera sight" while "he can be heard crying."
The baby then "cries for a few seconds until a thud or hit is heard," and "crying suddenly stops," according to the court documents.
After Li's "attempt to wake him up" is "no success," police say the video then shows that Li "shakes him."
The warrants obtained by 7 on Your Side Investigates show multiple images of the baby's head after Li allegedly shook the child.
Li remains at large. "Her whereabouts are currently unknown," said Castro.
The court documents also show images of teachers and nannies inside the Arcadia home with a group of children in two rows of desks.
Detectives wrote that one image shows an adult "hitting a child in the face," while another child does "squats."
Another image shows "another child getting spanked" while face down on a desk.
Police say that while Zhang and Xuan were arrested and released, their investigation into them and what occurred in their home continues.
"The Arcadia Police Department is conducting an ongoing investigation in conjunction with the FBI," said Castro.
Eyewitness News has been repeatedly reaching out to Zhang to hear her and her husband's side of the story, but they have declined to comment.
While police want to speak to their nanny because of allegations of abuse, Zhang and Xuan have not been accused of harming their children.
