The police in Leshan, Sichuan, successfully cracked a large cross-regional underground banking network, involving 13 provinces across the country, involving up to 38 billion yuan. The police found that the gang provided "public-to-private" services without real business operations by controlling 24 shelf companies, and used virtual currency transactions to implement cross-border fund transfer. The operation information is complicated, and about 20 million funds and data are intertwined. After careful investigation, a total of 176 alleged offenders were arrested, and the main offender Wan was sentenced to 13 years and six months in prison. At present, the cases in various places are still under further investigation.
