散

干活累了，他摘下帽子，把头发散了下来。

Tired after working, he took off his hat and let his hair down.

把地上的纸张收集起来，不要弄散了。

Gather up the papers on the floor and don't scatter them everywhere.

大火熄灭之后，浓烟慢慢散到城市上空。

After the fire was put out, the thick smoke slowly spread across the sky above the city.

乌云散了，天空又变得晴朗起来。

The dark clouds dispersed, and the sky became clear again.
