Why did the Three Gorges ape cry?

The reason why the Three Gorges ape cried sadly can be explained from the following aspects:

1. Topographic factors: The mountains on both sides of the Three Gorges are steep and the water is fast. Apes often look for food and shelter in trees or cliffs. Because the terrain of the Three Gorges is complex and the living environment of apes is relatively difficult, their songs may have some sad feelings.

2. Natural environment: The Three Gorges area is rich in ecological environment, including forests, grasslands and rivers. However, due to the influence of human activities, such as deforestation and dam construction, these ecological environments have been greatly destroyed, and the habitat and food sources of apes have also been affected. These factors may cause apes to express sad emotions when singing.

3. Cultural background: In ancient literature, the Three Gorges is often used to describe the steep and tragic natural environment. For example, there is a poem in Li Bai's "Early Making Baidicheng" that "the apes on both sides of the strait can't stop crying, but the canoe has passed Chung Shan Man". These literary works may have left a sad impression of the singing of the Three Gorges ape-man.

4. Human feelings: human feelings for apes are usually sympathetic and caring, so the chirping of apes in some cases can easily cause people's worries about their fate and sad feelings.

In a word, there are many reasons for the sadness of the Three Gorges apes, including the influence of topography, natural environment, cultural background and human emotions.
