In 1848, the Illinois-Michigan Canal connecting the Great Lakes and the Mississippi River systems, and the railroads that cut through the East to the West were completed.

Zhu Wencong and his party took the train directly to Chicago, and it must be said that this city was indeed prosperous.

The transportation industry in Chicago was extremely developed and was called "the artery of America." It was the largest railway hub in America and also the largest inland port city in the world.

On August 12, 1833, the town of Chicago was established with a population of just 350 people.

On March 4, 1837, Chicago was elevated from a town to a city, yet the population was only 4,170 people.

However, in the next sixty-plus years, Chicago became one of the cities with the fastest population growth in the world; from 1870 to 1900, the population of Chicagoans skyrocketed from 299,000 to 1.7 million.
