动弹 (dòng tan): to budge

His leg was pinned under a rock, and it hurt so much that he couldn't move at all.

The box was too heavy; I couldn't budge it at all by myself.

That little bird was injured and lay on the grass, unable to move.

It was so cold that my hands were too numb to move, and I couldn't even hold a pen.

The traffic police told the illegally parked car to move immediately, but it couldn't budge for a long time because the engine was broken.
