The reason why glacier eggplant is called glacier is mainly for the following two reasons:

1. The area where this kind of eggplant grows is Jade Dragon Snow Mountain, where there are glaciers that do not melt all year round. Therefore, people call this eggplant "glacial eggplant", which means that it grows in glacial areas and may absorb the essence of glacier water, giving it a unique taste and characteristics.

2. The skin of glacier eggplant is cyan with purple lines on it. These lines may resemble the layers on the glacier, so it is called glacier eggplant.

The above are just speculations, and the origin of the specific name may require further investigation and research.
