The efforts of anti-money laundering of mainland China have been widely criticized all the time. From the past years’ statistics of mainland China, Hong Kong, Macao and Taiwan, it seems that the efforts of mainland China are far beyond satisfactory. However, after comparing the crime circles of money laundering in these four areas, it was found that the above unsatisfactory situation was stemmed from the phenomenon in which the crime circle of money laundering of mainland China was too narrow to include enough criminal activities. Therefore, by introducing the concept of comprehensive money laundering crime, the statistics of crime of money laundering in mainland China are significantly increased and the rate in the entire criminal cases has also stayed on the same page with other three areas.
