Interest chain behind request for obtaining abolished certificates

AS EARLY AS MARCH 2015, the State Council, China's Cabinet, canceled 67 vocational certificates and approvals. However, the bureau of housing and urban-rural development in Haikou, South China's Hainan province, recently issued an official document requiring all local interior decorators to have two of the canceled certificates. Beijing Youth Daily comments:

Does the local government of Haikou know they are acting against the executive order of the central government?

There are various laws regulating the market, and all the local authorities need to do is to enforce them so that those breaking the laws get their deserved punishments. There is no need for the local government to intervene with their own measures.
