: Eleven years ago, Han Qiaosong's sister Han Fusu and her stepmother went to the United States for a trip, but they came back without her sister. When asked about the cause of the incident, the crying stepmother said that something happened while in the casino, and Fusu suddenly disappeared. By the time they thought of looking for someone, it was too late, and Fusu had already disappeared. Although they started searching immediately after that, it was of no use.
Qiao Song, who was still young at that time, did not agree with this statement. The elders in the family were furious and used all means to look for it, but only found a body said to be Fusu's.
