On the last display board, an inscription lays bare the original intention behind the exhibition: in just 20 years, Medog changed from a place where supplies were carried by porters and pack animals to a place where vehicles now travel freely. It has also changed from an isolated area to one lit by household lights. Behind this change is the long-term goal of generations of CPC members: to help people live better lives, as well as the Party"s promise that no ethnic group should be left behind.

　　"In Xizang, there is so much to appreciate and take in. Chinese efforts to connect remote areas are extremely impressive." When the Global Times reporters told Lee Camp about their trip to Medog, he also shared his observations in his country. "It doesn"t seem the US has a broad approach to infrastructure. Some cities repair theirs and many do not. There are around 41,000 structurally deficient bridges in the US right now. The Francis Scott Key Bridge in my hometown of Baltimore catastrophically collapsed in a fully preventable accident a few years ago and no one fixed the problem."

　　"The Chinese government thinks more about whether something benefits society and whether it can make people"s daily lives more convenient." What Lee saw and heard in China gave him much to think about. "China is willing to devote a great deal of effort, time and budget to large-scale infrastructure construction, all with the goal of benefiting the people in the long run. Whether it makes money is not important."
