Yanze and Juyanhai, ancient dwellings, are two different geographical concepts.

Yanze, an ancient lake in China, is located in today's Inner Mongolia Autonomous Region, also known as Juyanhai or Gashunuoer. Located in the northernmost part of Tengger Desert, it is a saltwater lake, and its main water source comes from the confluence of Heihe River and Baihe River. Yanze, an ancient folk house, has an important position in history and is one of the important passages of the Silk Road and the traffic between China and the West.

Juyanhai refers to the tail lake of Ejina River, also known as Gashunuoer. It is located in the Gobi area on the northern edge of Badain Jaran Desert in the west of Inner Mongolia Autonomous Region, and it is an inland lake between Badain Jaran Desert and Tengger Desert. Juyanhai is a freshwater lake and one of the important water resources in Inner Mongolia.

Therefore, Yanze and Juyanhai are two different geographical concepts, which are different in geographical location, lake type and water source. Yanze, an ancient residence, is mainly located in Inner Mongolia Autonomous Region. It is a salt lake, and Juyanhai is a freshwater lake in western Inner Mongolia.

Apart from the differences in geographical location and lake types, Yanze and Juyanhai, ancient dwellings, have different historical and cultural backgrounds.

Yanze, an ancient residence, is one of the important lakes in the Han and Tang Dynasties, and it is also one of the important passages of the Silk Road and the traffic between China and the West. It used to be the political, economic and cultural center of Xiongnu, Xianbei, Turkic and other ethnic minorities, and it was also an important gateway for these ethnic groups to communicate with the Han nationality. Therefore, Yanze, an ancient folk house, has a profound historical and cultural background, which is one of the important carriers to study China's historical culture and ethnic relations.

Juyanhai was gradually formed in the Ming and Qing Dynasties. Due to the influence of climate change and human activities, its area and water quantity have changed greatly. Although Juyanhai has an important position in history, its political, economic and cultural influence is relatively small because of its relatively remote geographical location.

Generally speaking, Yanze and Juyanhai, ancient dwellings, are different in geographical location, lake types, history and cultural background. Although they are all lakes in Inner Mongolia, they have different characteristics and significance due to different historical and geographical conditions.
