The reporter's investigation found that Hualai black tea was repeatedly attacked by public security organs all over the country, but it was never stopped. Founded in 2007, Hualai Bio, although claimed to be "direct selling" rather than pyramid selling, has not yet obtained the direct selling license issued by the Ministry of Commerce. According to informed sources, Hualai Bio, which sells black tea through pyramid schemes, can achieve a scale of several billion a year. No matter what marketing method is adopted in private, an enterprise with such a large volume will certainly be able to solve many problems easily. Hualai black tea not only has Hunan's "umbrella", but also has legal companies as cover. Such an enterprise, which has a tea garden and a factory, can see and touch everything, often makes news reports and is inspected by local leaders, claiming to be a "three rural projects strongly supported by the Hunan Provincial Party Committee and the provincial government, mainly undertaking the promotion and sales task of the second pillar industry black tea." An important reason why many people participate in "Hualaijian" pyramid scheme is that they believe too much in the company's self-promotion.
