How to write a 2-word summary of the canal story?

The Grand Canal has been flowing for more than 2,5 years. The Han Gou, the earliest section of the Grand Canal, is considered as the beginning of the Grand Canal, because the excavation of this artificial canal also gave birth to a city-Yangzhou.

The China Grand Canal, which stretches for more than 2,7 kilometers, not only moistens the economy and culture on both sides of the strait, but also gives birth to many docks, villages and towns. For example, the Zhangjiawan Wharf in the eastern suburb of Beijing was born because of the Grand Canal.

in the Ming and Qing dynasties in China, it was once one of the busiest docks on the grand canal, and it was known as the "first dock of the grand canal". Not only that, it also has a great connection with the construction of Beijing.

The goods from the south that keep coming through the Grand Canal:

After landing in Zhangjiawan, they are transported to major markets in Beijing. At that time, there were all kinds of southern commodities such as silk from Suzhou and Hangzhou, porcelain from Jingdezhen, iron pots from Foshan and tea from Anhui.

In 146, Emperor Yongle began to build the city of Beijing on a large scale. Many construction materials had to be transported to Beijing from the south through the Grand Canal. Ships floated all the way along the Grand Canal, stored at the shore of Zhangjiawan Wharf and transported to Beijing.
