竟 (jìng): một cách bất ngờ

Yesterday at the bookstore, I unexpectedly ran into my elementary school deskmate whom I hadn't seen for ten years; we were both very surprised.

He usually studies very hard, but unexpectedly he didn't pass this exam, which surprised everyone.

We thought we would lose, but unexpectedly we won the match; everyone jumped for joy.

After all these years, this small restaurant is unexpectedly still open, and business is even better than before.

He looks so young, yet unexpectedly he is already the father of two children.
