Please use the rhetorical technique of duality to design an advertising slogan calling for the protection of the Yellow River.

The nine-bend Yellow River nourishes China, and the green trees on both sides represent China.

The Yellow River is located in northern China and is the main birthplace of Chinese civilization. The Chinese call it the "Mother River." The Yellow River has a total length of approximately 5,464 kilometers and a drainage area of ??approximately 752,443 km. It is the fifth longest river in the world and the second longest river in China.

The Yellow River originates from Maqu in the Yogu Zonglie Basin at the northern foot of the Bayan Har Mountains on the Qinghai-Tibet Plateau. It flows from west to east through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, and Shanxi. It flows through nine provinces, cities and autonomous regions in Henan, Henan and Shandong, and finally flows into the Bohai Sea in Shandong, taking the shape of a "ji", so it is called the "Yellow River with a few characters".
