Cultural Note

In Chinese culture, reflecting on the past is significant, and the use of 曾 in storytelling and historical accounts emphasizes the importance of memory and history. It is often found in literature and formal speeches when discussing past events.

Memory Tip

Imagine a grandfather (the great-grandparent) telling a story about 'once' when he was young; the character 曾 looks a bit like a person with arms raised in memory. The pronunciation 'céng' sounds like 'sung,' as if he is singing about his past adventures.
