What are the two boards and three columns of the property bulletin board?

There are two boards and three columns in the property publicity column, namely, the charging service publicity column, the service supervision publicity column, the community information publicity column, the public income publicity column, and the policies and regulations publicity column. The deputies to the street people's congress asked the property service enterprises to rectify the existing problems as soon as possible and fulfill their responsibilities, and stressed that the property service enterprises should do a good job in setting up the "two cards and three columns" (charging service publicity column, service supervision publicity column, community information publicity column, public income publicity column, policies and regulations publicity column), standardize enterprise behavior, seriously publicize community public income, and further standardize public income.
