骡子

骡子 (luó zi) is the Chinese word for 'mule,' a hybrid animal resulting from crossing a horse and a donkey. Unlike horses or donkeys, mules are typically sterile and known for their strength, endurance, and stubbornness.

The character 骡 (luó) originally referred to a mule, while 子 (zǐ) is a common suffix used to denote a young or small version of something, or to form nouns. Together, they form a term specifically referring to the animal.

In Chinese culture, mules are often used for transportation in rural areas due to their hardiness. The term can also be used metaphorically to describe someone who is stubborn or difficult to handle.
