How come the resettlement house in Jiashan has only planned six floors?

The reason why Jiashan's resettlement houses only plan six floors is the policy reason. The Ministry of Housing and Urban-Rural Development, the Ministry of Science and Technology, the Ministry of Industry and Information Technology and other departments 15 recently jointly issued the Opinions on Strengthening Green and Low-carbon Construction in Counties, stipulating that the newly-built houses in counties should be mainly six floors, with the construction area of six floors and below not less than 70%, and the newly-built houses in counties should not exceed 18 floors at most.
