Chen Guangbiao, a Chinese entrepreneur and philanthropist, decorated a temporary television studio with 16 metric tons of 100-yuan notes to promote the upcoming national economic census in Nanjing, capital of East China's Jiangsu province, on Dec 24, 2013. The cash was transported to the studio in a large truck and it took 20 people five hours to decorate the tent-turned-TV-studio with the cash, China News Services reported Wednesday. Chen said this is the sixth time that he used money as background for charitable promotions since 2010, and the amount of money is the largest this time. Chen also said he welcomes investigation of his business. The nationwide economic census will start on Jan 1. Chen's total worth was estimated at 3.5 billion yuan ($576 million) in 2010, according to a Hurun Wealth report. [Photo/icpress.cn]
