The meaning of this character varies a lot depending on context. These meanings include dry, clean, foster, adoptive, heaven, male, masculine, enduring, or continual.

The “Gan” version of this character was converted to Simplified Chinese as 干 in 1965. However, the “Qian” pronunciation is not associated with 干. Though to add to the confusion, there is an unrelated Simplified Chinese character 千 that romanizes as “Qian” and is also a surname.
