The Origin of the Name

The name "SiYuan" (思源) comes from the ancient Chinese idiom "Drink water and think of its source" (饮水思源). Literally, it means "When drinking water, remember where it comes from," symbolizing gratitude and never forgetting one's roots.

We hope that while using SiYuan Note for knowledge management, users will:

Remember the origins and connections of knowledge,

And more importantly, never forget to give back to society and humanity through what they’ve learned.
