On June 26, 2007 (May 12, 2007 in the lunar calendar), Du's underground bank was destroyed. On June 26, 2007, the police in Shenzhen and Guangzhou took a concerted action and destroyed two underground bank houses located here. Six suspects, including Du Ling, the owner of an underground bank, were arrested on the spot, and 55 accounts involved in the case were frozen with an amount of approximately RMB 4.2 million. According to investigation, Du's underground bank has been operating illegally in Shenzhen for seven or eight years. From 2006 to May 2007, the transaction amount of the Shenzhen office alone reached more than RMB 4.3 billion. The shocking case of Du's underground money bank in Shenzhen is located in Daxin Building on Bao 'an South Road in Luohu District. It is only 200 meters away from Shenzhen's landmark Diwang Building, but there are four or five commercial bank business locations scattered around it. "Low-key and hidden, densely populated with banks, and mixed with commercial and residential properties, it is often the most popular place for underground banks." A person familiar with the matter told reporters. At about 11 a.m. on June 26, Xiao Liu, who was preparing to shift shifts, saw four or five public security bureau vans suddenly coming to the door."Twenty or thirty police officers came down and asked me to take them to the 22nd floor. After knocking on the door, two people are sitting in front of the computer." According to a police officer involved in the arrest, Du Ling, the owner of the bank, who was dressed in black, saw the police coming in and said,"It looked like a seizure. It was obvious that it was fake at first glance." After being discovered, she knew that she could not escape, so she opened the safe and "seized 90 bank cards of various types, 40 online banking keys, 67 passbooks, 11 ID cards for transfer, and more than 30,000 yuan in cash on the spot." Du Ling and five staff members involved in the case were arrested. At the same time, the arrest team in Guangzhou also closed the net. Bao Wei, the head of the Guangzhou office of Du's underground bank, was arrested on the spot. After statistics on the transaction records seized, it was found that from the beginning of 2006 to May this year, the amount involved in Shenzhen dens alone was as high as 4.3 billion yuan, mainly involving foreign exchange trading, and a large amount of illegal funds have flowed into the stock market and property market. Among them, transaction funds related to real estate reached 130 million yuan, and transaction funds related to the capital market reached 105 million yuan. The largest amount involved was in trade, sales and other industries, with funds reaching 453 million yuan. Coupled with the amount involved in the case in Guangzhou's dens of 2.2 billion yuan, the total illegal capital flow of 6.5 billion yuan is only statistics in the past two years. According to police, the Du's underground bank has existed for seven or eight years. "With a few computers, two phones, and two fax machines, the transaction amount is as high as 8 million yuan per day, and a transaction can be completed every 3 minutes." A person familiar with the matter analyzed to reporters,"Nowadays, underground bank owners are becoming more and more savvy. They are constantly studying ways to deal with the country's anti-money laundering, minimizing cash transactions, and making online banking convenient and safe. "The transaction list shows that Du's underground bank involves customers in 31 provinces, cities and autonomous regions across the country. Unlike the underground banks investigated in the past, which were mainly individual customers, a large number of foreign trade and investment companies have attracted the attention of case handlers. Even well-known state-owned enterprises are involved. Du Ling, the queen of Qianyuan, was born in Lianshan Zhuang and Yao Autonomous County, Qingyuan City in the 1960s. After graduating from junior high school, Du Ling helped look after the store in the canteen opened by her father. Until the 1990s, when the family moved to Foshan, she went to Shenzhen to work alone. She was introduced to work in a Hong Kong dollar exchange shop near Luohu Port. Du Ling's career history is relatively unfamiliar and mysterious, whether in her hometown or Shenzhen. The most consistent guess is that Du Ling, who has been engaged in Hong Kong dollar exchange for a long time, established her own business after accumulating certain customer resources. During this period, she even met Deng Guoliang, who runs a RMB exchange bank in Hong Kong. After the two got married, Du Ling moved to Hong Kong and jointly organized the exchange of RMB between China and Hong Kong. Du served as chairman and Deng served as general manager. Du Ling, the heroine of the Qianzhuang case, has at least thousands of exchange shops in Hong Kong such as the China-Hong Kong RMB exchange line change. Du Ling's company is not well-known in Hong Kong. However, due to the huge profits from underground bank transactions in the mainland, many Hong Kong stores have offices in the Guangzhou and Shenzhen area to facilitate currency trading between the two places. After Du Ling's accident, six or seven stores in Hong Kong where RMB was exchanged between China and Hong Kong remained open as usual and were not affected. In Du Ling's hometown, the cracking of the underground bank case is becoming the hottest topic in the streets. Lianshan County is located in the northwest of Guangdong, at the junction of Guangdong, Hunan and Guangxi provinces (regions). Among the county's 120,000 people, Zhuang and Yao account for 63%. It is a key poverty alleviation and development county in Guangdong Province. Compared with the title of "Qianzhuang Queen", people's impression of Du Ling remains more as "a famous person in Lianshan who donated generously." To this day, there is still a commercial street named after Du Ling in the county. According to a staff member of the Propaganda Department of the County Party Committee, in the past few years, the County Housing Management Bureau renovated the commercial street and called on Lianshan entrepreneurs to donate money. Du Ling donated the money and named it after her. The commercial street opened during the 40th anniversary celebration of Lianshan County in 2002. Du Ling also attended the unveiling ceremony as a guest of Hong Kong and Macao. As for what business Du Ling was engaged in outside, local people and cadres said that they were "not very clear". Du Ling Commercial Street Du Ling is active in the business world and is a famous businessman in Qingyuan City. The picture shows a photo of her with Hong Kong artist Miao Qiaowei.
