It Takes Him 6 Years To Transfer Stones To His Building Roof

Professor Zhang Lin spent a period of 6 years to move the stones on the roof of his building, where shrubs and herbs grow.

Strangely enough, he did not get any approval prior to construction, says the local administration of the city of Beijing that if it is found that the risk of the architecture will be torn down, and residents of the building complained that there are cracks and leaks due to the weight of the stones which they built their neighbor.
