Excuse me, is Uliji of Mongolia a surname?

In Mongolian, "Wuliji" means "auspicious and beautiful" and is often used by elders to wish their children happiness in the New Year.

I don't think it's a last name, it's a first name. Mongolian names are mostly based on their own psychological habits, with rich colors and distinctive features.
