In 2024 Wei began to suspect He of cheating. He left home often, saying she went to job interviews or met friends. Some family members said they saw her with another man, and they also saw her unplug the home cameras and the car dash‑cam.

In April 2026 Wei collected DNA samples from the twins. The test showed that he was not their biological father. He then asked for a test for the eldest daughter, and that test gave the same result.

He (the wife) did not accept the first results and asked for a formal forensic test. The court ordered a fourth DNA test, and the court‑ordered test confirmed that Wei is not the biological father of any of the three girls.

Wei filed for divorce in June. At the hearing on August 17, he asked the Nanzheng District People’s Court to order He to pay about 310,000 yuan for child‑rearing costs and emotional distress.

He said she does not know who the real father is. She offered to pay 10,000 yuan for each child, but Wei rejected the offer. The court gave custody of the children to He and postponed a final decision on compensation.
