Beside the smashed windows on the ransacked building of a direct marketing company, graffiti vows revenge on managers who ran away with the sales agents' life savings. The scene is in Shenzhen but a government ban has seen such companies closed down across the nation. Many agents stuck with goods they have paid for but can no longer sell have adopted a wait-and-see approach, but others are planning to get around the ban by selling their unsold goods in Hong Kong. Others have heeded government advice to return to their home provinces, but some are pinning their hopes on the Government relaxing its ban or compensating their losses. Last week, thousands of sales agents protested at companies in Shenzhen as they returned their goods - including health-care products and body-building machines - for refunds. 'Most of them have gone home after receiving a few hundred yuan from the municipal Industry and Commerce Bureau,' said Huang Wenyi as he camped outside a firm in Binjiang Mansion. On the wall, close to where he sat, were the words: 'Go to hell, Zhu Fuming [a manager].' More damning graffiti runs along the walls. Mr Huang, in his 20s, said he had been told of one agent who jumped to his death from a nearby building after losing his life savings because of the ban. Trained as a computer graphic artist, Mr Huang went to Shenzhen from Henan about a year ago. He put all his money into direct selling and did not have the heart to tell his family things had gone wrong. Guangdong Industry and Commerce Administration, in charge of the management of retail markets, has announced it is the responsibility of the direct sales companies to refund agents, insisting the Government will not compensate them. In front of the Kangda company office in Shenzhen's Longgang district, Liu Yuqin was busy networking instead of waiting for help from the Government. Here, more than 1,000 agents from Sichuan, Gansu, Jiangsu, Heilongjiang and Jilin provinces descended last month to return body-building machines for cash. Most left disappointed. Mr Liu, in his 40s, held out a contract saying he had recruited several hundred agents who had failed to return their goods. They would continue direct selling for a company in Hong Kong, he said. 'Since China is practising 'one country, two systems', there is no way they are going to stop us,' insisted the would-be businessman. A man standing near him, also from Jiangsu, said he had already signed up.
