How do you spell xian?

"Xian" can be spelled in a few different ways, depending on the context and the specific meaning you're trying to convey:

* Xi'an: This is the most common spelling and refers to the capital city of Shaanxi province in China.

* Xian: This spelling is also used, but it's less common and can be confusing as it's often used for other things like "immortal" or "fairy" in Chinese.

It's important to consider the context to determine the correct spelling. If you're referring to the city, then "Xi'an" is the correct spelling. If you're referring to something else, you may need to provide more context or specify the meaning you're trying to convey.
