I enjoyed horse riding by putting a bit on the horse.

His spine is straight, and he has good posture.

He is using special tools to carve wood.

He did not understand the meaning of '戮' (kill).

He took a foolish action.

His grades were not satisfactory.

I think he is a decent human being.

I have never seen land.

There are a lot of butterburs growing in my garden.

His body is trained by healthy eating and exercise.
