This work was made in collaboration with Raphael Bourelly.Over time since Antiquity, observing nature has been elevated to the ranks of an art form. The traditional painting "Shan Shui", meaning "Mountains Water", perpetuates in Chinese culture the tribute to water courses and mountains. But nowadays, the regions of central China, where a booming industrialization and urbanization are taking place, are at the heart of the current government agenda - and defy these traditions. Irrigated by the sole Yellow River and spreading up steep contours, they represent the many challenges which regularly occur. Despite being known since time began as the "Mother River", many incidents of river pollution have taken place in this part of the region in the past decades. It is also in these regions that the Chinese government has initiated the flattening of numerous mountains in order to encourage urban development and economic activity.
