忍 (rěn): bear to bear

When the dentist drilled her tooth, she was in so much pain that she could hardly keep from crying out.

He put up with it for three years and finally summoned the courage to ask his boss for a raise.

In the crowded subway, he endured his foot pain and gave up his seat to a woman holding a child.

Facing her colleagues' ridicule, she held back her tears and continued to focus on her work.

This kind of pain was truly unbearable, so the doctor gave him a painkiller injection.
