Economist Yao Yang, Dean of the Dishui Lake Advanced School of Finance at Shanghai University of Finance and Economics, said in a video posted on "Yao Yang Shuo" that about 100 million people in China actually pay individual income tax, that an annual income of 100,000 to 120,000 yuan puts one in the top 10% by income, and that an annual income of about 300,000 yuan puts one in the top 1%. The bottom 10% of earners account for only 0.4% of all income and have negative net wealth, and around 600 million people nationwide still earn less than 1,000 yuan per month.
