Usage Notes
由此 is a formal and literary connective. It is primarily used in written Chinese -- academic papers, news editorials, and formal reports. In spoken Chinese, 因此 (yīncǐ) or 所以 (suǒyǐ) are more natural alternatives.
The phrase 由此可见 (from this it can be seen) is one of the most common fixed expressions using 由此 and frequently appears in concluding sentences of paragraphs in argumentative writing. Unlike 因此, which simply means "therefore," 由此 places emphasis on the specific evidence or situation just mentioned as the basis for the conclusion.
Memory Hook
由 (from/due to) + 此 (this) -- from this specific point -- hence, thus.
