Qian zeyouzuo updated his twitter on Tuesday to explain why he held such a high lottery this year. This years draw is a social experiment, he said. He will get in touch with the winners and have them participate in future experimental investigations on a regular basis. The aim of the experiment was to see if getting a million yen makes life happy.. Qianze also said that if everyones life is more comfortable, they will be engaged in the work they like and will also spend their time on creative activities. The final result should be to increase work efficiency, income and consumption, and overall economic efficiency. He also said he would work with sociologists and economists to complete the social experiment.
