Imagine a pathway (由) leading to a destination (此), representing how one idea leads to another. The 'you' in 'you2' sounds like 'you are here', indicating the starting point of a discussion or argument.

Be careful not to confuse 由此 with similar phrases like '因此' (yīn cǐ), which means 'therefore'. 由此 is more formal and often appears in written Chinese, while '因此' is more commonly used in conversation. Remember to use it in contexts that require clarity of consequence.

While 由此 is not part of the HSK vocabulary list, it connects well with other formal expressions at higher levels. Focus on understanding its use in written Chinese and how it relates to cause-and-effect structures in sentences.

The phrase 由此 is often used in legal and official documents in China to denote binding conclusions, reflecting the importance of clear and logical reasoning in Chinese bureaucracy.

Learners often confuse 由此 with 由来 (yóu lái), which means 'origin' or 'source'. For example, saying '我们由此开始' (Wǒmen yóu cǐ kāishǐ) is correct, but using '我们由来开始' is incorrect.
