It didn't because the zhou was the king of the shang dynasty

yes

Once the Shang where captured by the Zhou the Shangs king killed himself. The Shang joined the rebellion but it collapsed and the Zhou Dynasty stared.

On January 20, 1046BC, Zhou Wu Wang, Ji Fa, duke of the state of Zhou, led his troops into the capital of the Shang Dynasty. The king of Shang, Shang Zhou, burned himself to death Shang Dynasty was extinguished, so that Zhou Dynasty was founded.

The last king of China would be Bo Yee (this is the pinyin for his name). I'm canto so the pinyin may be different if you speak mandarin.
