The Chinese word **过关** (guòguān) is a verb-object compound formed by combining the character **过** (guò), meaning "to pass" or "to cross," with **关** (guān), meaning "a pass," "barrier," or "checkpoint." It originates from the literal act of passing through a strategic frontier gate or military checkpoint. Over time, its meaning expanded metaphorically to describe successfully overcoming any challenging test, inspection, or difficult stage—much like advancing to the next level in a game—making it a common expression for meeting standards or conquering obstacles.
