青海杉

'青海杉' can be translated as 'Qinghai Fir', combining the region name 'Qinghai', a province in western China well known for its lakes and ethnic cultures, with 'fir', a type of evergreen tree. The username symbolizes someone who is steadfast, enduring, or resilient like a fir, and perhaps has a close connection to nature or a specific attachment to Qinghai.
