In her 1000-word note, Dai, a homemaker, said that, after He went missing, she lost the will to live in the face of growing family pressure.
She wrote that He's family complained that she spent too much money and was mentally ill. They also opposed her plan to get a job in the city, according to the note, which was widely shared online.
"I wanted to leave by myself, but thinking that my children would suffer without both their parents, I decided to take them with me," wrote Dai, who it was revealed had lost both of her parents when she was young.
Local police said He had resorted to the insurance fraud because he was more than 100,000 yuan ($22,000) in debt. In a video posted by the WeChat public account, Xinhua Focus, over the weekend, He was shown kneeling on the ground and wailing for his wife and children.
He said he went to Guizhou after engineering the accident, but returned after seeing his wife's note online. He also said in the video that he was in debt because of his daughter's illness and his car loans.
He's family confirmed the girl had been diagnosed with epilepsy last year and had since been on medication, according to Beijing Youth Daily.
Calls to the county's police bureau and publicity department went unanswered.
