What are the three natural features that the Grand canal connects?

The Grand Canal in China connects three major natural features:

1. Hangzhou Bay: The Grand Canal begins in Hangzhou, a city located on the eastern coast of China, at the southern end of Hangzhou Bay. This bay is part of the East China Sea.

2. Yangtze River: The Grand Canal joins the Yangtze River at its northern end. The Yangtze River is the longest river in China and the third longest in the world.

3. Yellow River: The Grand Canal also connects with the Yellow River, one of the most important rivers in China, at its southern end. The Yellow River is often called the "cradle of Chinese civilization" and is the second longest river in China.
