Overview

Yilishen Tianxi Group was a Chinese company established in 1999 by Liaoning businessman Wang Fengyou. It marketed traditional Chinese medicine and health products whose principal ingredients were ants, including ant-based pills, wine, and a product promoted as an alternative to Viagra. The company operated under the Yilishen name and built a substantial consumer presence through television advertising, celebrity endorsements, distribution through Chinese pharmacies, and public-facing charitable and civic donations. Its most consequential business activity was not ordinary retail sales but an ant-breeding investment arrangement. Customers, many of them unemployed factory workers, rural residents, or other households with limited financial resources, paid for boxes of black mountain ants and were instructed to raise them using sugar water, egg yolk, cake, and other feed. Yilishen promised to repurchase the mature ants after roughly three months at a substantial return. Reported returns ranged from approximately 30 to 60 percent, encouraging participants to reinvest their proceeds and purchase additional ant boxes. The company processed dead ants into health products, including pills and wine, and claimed a broad distribution network reaching more than 50,000 pharmacies. Yilishen’s public image benefited from celebrity and official associations. Television advertising featured Bao Xishun, known at the time as China’s tallest man, and comedian Zhao Benshan. Wang Fengyou was photographed with Bo Xilai, then a senior Chinese government official, and the company received a direct-marketing license in 2007. Wang was also recognized in a national entrepreneurial ranking. These associations were perceived by many participants as evidence that the business was legitimate and had official support. The model began to fail in 2007 as sales of the underlying health products declined. Accounts described the company as relying increasingly on money from new participants to meet obligations to earlier investors, rather than generating sufficient operating income from product sales. In November 2007, the company failed to make promised payments, leading to large demonstrations in Liaoning. More than 10,000 investors were reportedly confronted by riot police in Shenyang, while other groups protested outside government buildings. Wang Fengyou was arrested on 7 December 2007 by public-security authorities in Liaoning in connection with alleged disruption of public order. His arrest and a televised confession followed protests by ant farmers. The company subsequently entered liquidation. The collapse caused severe losses for participants, including people who had invested family savings and retirement funds. Reports also described suicides, self-immolation, intimidation, arrests, and alleged police violence connected with the protests. The Yilishen case became one of the most prominent examples of a failed Chinese ant-breeding investment scheme and contributed to public concern about fraudulent investment programs presented as health-product or direct-selling businesses.

History

Yilishen Tianxi Group was founded in 1999 by Wang Fengyou, a businessman from Liaoning. It developed and sold health products presented as traditional Chinese medicine, using ants as a principal ingredient. Its product range included ant-based pills and wine, as well as a sexual-health product promoted as an alternative to Viagra. The company manufactured products from ants collected or raised through its network and reportedly distributed them through tens of thousands of Chinese pharmacies. The company’s defining commercial mechanism was an ant-breeding arrangement marketed to households as a source of investment income. Participants purchased boxes containing black mountain ants, raised them according to prescribed feeding instructions, and were promised that Yilishen would buy the mature ants back after approximately three months. Reported returns of 30 to 60 percent encouraged many participants to reinvest their proceeds. The arrangement attracted large numbers of people, particularly unemployed workers, rural residents, and families seeking an alternative source of income. Yilishen operated a factory that processed dead ants into pills and wine, providing a product-based explanation for the breeding network. Yilishen also invested heavily in public visibility. It advertised on television and used endorsements from Bao Xishun and Zhao Benshan. Wang Fengyou was photographed with Bo Xilai, and the company received a direct-marketing license in 2007. Wang was named in a national entrepreneurial ranking. These connections and official associations helped create an impression of institutional legitimacy among customers and investors. The company also made reported donations totaling about US$1.4 million to charitable causes and the 2008 Summer Olympics, including support associated with infrastructure in Liaoyang. Allegations later emerged that the company had paid bribes to officials in exchange for favorable treatment, although the supplied reference does not establish the outcome of those allegations. The business deteriorated in 2007 when demand for its health products fell. According to accounts of the collapse, Yilishen increasingly depended on money from new participants to provide income to earlier participants. Once the flow of new funds was insufficient, it could not meet the promised repurchase and return obligations. In November, investors began protesting after payments were missed. More than 10,000 people were reportedly involved in demonstrations in Shenyang, and other ant farmers gathered outside government offices. The protests drew a forceful response from police and became a highly visible social and financial crisis. On 7 December 2007, Wang Fengyou was arrested by Liaoning public-security authorities for alleged disruption of public order. Local television broadcast his arrest and confession, in which he was reported to have acknowledged responsibility for instigating protests. Yilishen subsequently entered liquidation. Participants reportedly lost life savings and pensions, and press accounts described suicides, an attempted self-immolation in Tiananmen Square, surveillance fears, short-term arrests, and alleged beatings of protesters. Some investors were reportedly required to register with local authorities, while the availability of compensation remained uncertain. The collapse was part of a broader pattern of ant-breeding schemes in China. In February 2008, a different man in the same province received a death sentence for defrauding investors of three billion yuan in a similar scheme. Yilishen’s failure is remembered as a major case in which a purported health-products enterprise used a tangible commodity and direct-selling language to support an investment proposition that ultimately proved unsustainable. The company is now defunct and no longer operates as an active consumer brand.

Products and positioning

The company positioned itself at the intersection of traditional Chinese medicine, consumer health products, direct selling, and household income generation. Its commercial narrative combined purported health benefits from ant-derived products with an investment proposition promising rapid returns from breeding and reselling ants. This dual positioning helped it reach consumers beyond conventional medicine buyers, but also blurred the distinction between product sales and investment solicitation.

  • Traditional Chinese medicine and supplements

    Ant-based health products

    Yilishen marketed health products made with ants as a principal ingredient. The products were promoted through television advertising and distributed through a large Chinese pharmacy network. The company presented them as traditional Chinese medicine or health products rather than ordinary food commodities.

  • Health supplement

    Ant-derived pills

    The company manufactured pills using ants supplied through its breeding network. These products formed part of the commercial rationale for purchasing and raising ants, although the investment program became more central to the company’s public controversy than the retail products themselves.

  • Traditional medicinal beverage

    Ant-based wine

    Ant-breeding investment boxes

    Participants bought boxes of black mountain ants and were told to raise them with sugar water, egg yolk, cake, and other feed.
