* Wēi (wei1): This is the most common pronunciation and is pronounced with a high, rising tone. It sounds similar to the English word "way," but with a slightly higher pitch.
* Wěi (wei3): This pronunciation is less common and is pronounced with a falling-rising tone. It sounds similar to the English word "way," but with a dip in the middle and then a rise at the end.
It's important to know which tone is used in the specific context because the meaning of the word can change depending on the tone. For example:
* Wēi (wei1): This can mean "danger" or "threat," but can also be used in a person's name.
* Wěi (wei3): This often means "tail" or "end," but can also be used in a person's name.
To be sure of the correct pronunciation, it's always best to check the context or ask a native speaker.
