What does the last sentence of city light mean?

We live in the landscape city of Changshu, and "the mountain of the world, the mountain of Changshu" contains her meaning.

Changshu's "landscape culture" has remarkable characteristics. Known as the "Little Great Wall in the South of the Yangtze River", the ancient city wall of Changshu winds on Yushan Mountain. Shang Hu in front of the mountain tells the story of fishing in Jiang Ziya for thousands of years, and the East Lake currently being developed has become two mirrors embedded in Changshu. One mountain and two lakes embrace the ancient city of Changshu.

In particular, Yushan Shang Hu Scenic Area, with beautiful scenery and intoxicating landscapes, is a good place for Changshu citizens to relax. Changshu's urban construction is advancing by leaps and bounds. The spacious and flat asphalt roads, beautiful tall buildings, speeding cars and beautiful buses add a modern atmosphere to the city.
