悠 (yōu): leisurely; unhurried; relaxed

After Grandpa retired, his life became very leisurely: every morning he goes to the park to practice tai chi, and in the afternoon he reads and drinks tea at home.

The exam was finally over; he lay on the sofa unhurriedly, listening to light music and completely relaxing.

On the weekend we rented a small boat and drifted leisurely on the lake, enjoying the breeze and sunshine.

He speaks slowly, with a long, drawn-out voice that makes people feel very reassured.

The sound of the mountain temple bell carried melodiously, and the whole village was immersed in the quiet night.
