Wu said that the police in Leshan, Sichuan Province, successfully cracked a large-scale cross-regional underground money bank criminal network involving 13 provinces across the country, with a total amount of 38 billion yuan involved. The police found out that the gang controlled 24 shell companies, provided "public-to-private" services without real operations, and used virtual currency transactions to implement cross-border fund transfers. The operation information was complex, with about 20 million fund data intertwined. After careful investigation, a total of 176 suspects were arrested, and the main culprit Wan was sentenced to 13 years and six months. At present, cases in various places are still under further investigation.
