He is a brave firefighter.

This festival is held every year.

He solved the problem rapidly.

I'm always amazed at the speed of his work.

The fire department works around the clock to prevent fires.

He was immersed in his work all day.

He was working all day.

This flower is very rare.

He is studying the ancient Chinese poison, Chin.

I, the emperor, wish for the happiness of the people.
