The earliest statement about the cause of Gao Xiumin's death was the loss of a middle-aged son, because 10 days before Gao Xiumin's death, He Qingkui's son died in a car accident in Guangzhou, and Gao Xiumin and He Qingkui were husband and wife. Later, an informed person revealed that Gao Xiumin died of drug overdose. Her "old partner" He Qingkui was also a drug addict. They were once arrested by the public security experts bureau. Of course, He Qingkui did not agree with this view. According to He Qingkui, Gao Xiumin had the problem of snoring. In fact, it was caused by the cessation of breathing in the middle of the night due to snoring. He Qingkui said that Gao Xiumin's face was very purple after death.
