Panda's ears are called 'ears' in English, just like in Chinese. However, there are some interesting facts about panda ears that are worth mentioning.

Firstly, panda ears are unique in their size and shape. As a panda's head is quite round, their ears are also relatively small and circular. This is in contrast to other bear species, whose ears are typically longer and more pointed.

Secondly, panda ears are covered in fur, both inside and out. This helps to keep them warm in the cold mountainous regions where they live. It also helps to muffle sound, which is useful for hunting prey and avoiding predators.

Lastly, panda ears are also used for communication. When a panda is feeling threatened or aggressive, they may flatten their ears against their head as a warning signal. Conversely, when they are feeling calm and relaxed, their ears will be in their natural upright position.

In conclusion, while the English word for panda ears is simply 'ears', there are many interesting facts about their size, shape, fur covering, and communicative functions that make them unique and fascinating.
