通过 (tōngguò) vs 过关 (guòguān): Use 通过 when emphasizing the process of passing through or completing something, while 过关 focuses on successfully meeting a specific standard or overcoming a hurdle.

Imagine a person crossing a gate (关) that has a 'pass' sign on it. The character 过 means 'to pass' or 'to cross,' and when combined with 关, it creates an image of successfully passing through a gate. Visualize someone joyfully running through the gate after overcoming a challenge.

Be cautious not to confuse 过关 with simply 'passing' something; it implies overcoming a challenge rather than just achieving a score. It is generally used in both formal settings, like academic contexts, and informal ones, such as personal achievements. Remember that the tone of 过 (guò) is falling, while 关 (guān) is high and level.

Although not explicitly listed in HSK levels, understanding 过 and 关 separately can aid comprehension. Focus on the individual meanings of each character to better grasp the compound. This connects with HSK vocabulary related to tests and challenges.

In Chinese culture, the concept of passing tests, especially educational ones, is deeply ingrained, often determining future opportunities. The importance of 过关 reflects the value placed on achievement and perseverance in society.

Learners often mistakenly use 过关 in contexts where a simple 'pass' would suffice, such as saying 'I passed the exam' instead of 'I crossed the barrier of the exam.' Instead, use 通过考试 (tōng guò kǎo shì) to indicate simply passing an exam without the connotation of overcoming challenges.
