What does "three clean-ups, three dismantlements and three rectifications" mean?

1, the first third cleaning timely tidied up villages and lanes and production tools, littered building materials, and tidied up weeds and sundries in front of and behind the house. Stored wastes, classified ditches, ponds, streams and rivers, and other silt, floating objects and obstacles. All these are under the treatment of Sanqing.

2. The second demolition is to demolish old houses, abandoned pigsty and open-air toilet huts, and then demolish illegal buildings and some illegal billboards and signboards.

3. The third and third renovations are mainly to rectify the waste, domestic sewage and water pollution, and then beautify and green the village environment. The country is on the verge of three demolition actions, and three kinds of houses can't get any compensation. The first building was built on its own farmland, the second one was dilapidated for many years, and the third one was a house with low value.
