Abstract: From the human history, it can be seen that ignorance and shameless are two main reasons for our mistakes. In the history of Chinese economy, many officials and researchers believed that the correct prices could be calculated. Looking back, we now find this is incredible. Later, the dual system has solved this problem. The formulation of a number of policies nowadays, however, reflects our ignorance; after all, the only way out is the market economy. We should introduce competition and ensure the freedom of thought.

Key words: market economy; ignorance; shameless; competition
