Kultureller Hintergrund
The phrase utilizes 'Chi' (此), a classical Chinese pronoun for 'this,' giving it a sophisticated, scholarly vibe. It reflects a traditional emphasis on deductive reasoning often found in historical Chinese literature and legal texts. Today, it remains a staple in academic writing and professional journalism across the Sinosphere.
The 'Sherlock' Effect
Use this phrase when you want to sound like you've done some serious thinking. It transforms a simple guess into a logical deduction.

What It Means
Think of 由此可以得知 as the bridge between a clue and a discovery. It is a logical connector. It tells your listener that you aren't just guessing. You are making an educated deduction based on what was just discussed. It sounds smart and methodical. It’s like saying, "Based on these facts, we can conclude that..."
How To Use It
You usually place this at the start of a new sentence. First, you state a fact or an observation. Then, you drop 由此可以得知 to reveal the secret meaning behind that fact. It works best when the conclusion isn't immediately obvious. It makes you sound like you’ve really thought things through.
When To Use It
Use it when you are analyzing something. It’s great for business meetings when looking at data. It’s perfect for detective novels or mystery movies. You can even use it with friends when you're gossiping. "He didn't reply to your text for three days; 由此可以得知, he's just not that into you." It adds a bit of weight to your words.
When NOT To Use It
Avoid this if the conclusion is painfully obvious. If it’s raining and you say, "It's raining; 由此可以得知, the ground is wet," you’ll sound like a robot. Also, keep it out of super casual slang-heavy chats. It’s a bit too structured for a wild party or a quick "hey" to a close buddy. It can feel a bit stiff in high-energy, emotional outbursts.
Cultural Background
This phrase has a slightly classical feel. The word 此 (this) and 得知 (obtain knowledge) are more formal than their everyday counterparts 这个 and 知道. It reflects the Chinese value of logical reasoning and observation. It’s the kind of language used by scholars and strategists in historical dramas. Using it correctly shows you have a good grasp of formal sentence structures.
Common Variations
You might hear 由此可知 which is a bit shorter. There is also 由此看来, which means "looking at it from this perspective." If you want to be even more formal, you could use 由此推论. But 由此可以得知 is the sweet spot for B2 learners. It’s clear, professional, and very useful.
Nutzungshinweise
This expression sits in the neutral-to-formal range. While grammatically simple, it carries a tone of authority and logical clarity. Avoid using it in high-slang environments to prevent sounding overly academic.

Classical Roots
The word 'Ci' (此) is a remnant of Classical Chinese. Using it makes you sound more educated than using the modern 'Zhege' (这个).
