Citroen Park is a very familiar case. I studied her plane many times before I came to the scene, browsed her photos, and learned the background of the scheme and the origin of the idea from the articles published in various magazines. When I came to Citroen Park with the mentality of meeting old friends, I got a new experience - "without leaving any trace of the original Citroen automobile factory scheme, in fact, retained the most prominent historical features of the site; the amazing "plane" geometric layout depicted a "three-dimensional park"; the photograph depicted a neat shape and uniform appearance of the plastic plant behind. It is a very rich use of plant materials; the blood of this modern garden is still boiling with the blood of the French classical garden which lasted 300 years.
