Originally, Qingming didn't relate to tomb sweeping or showing respect to ancestors.

本来， 清明与扫墓、祭祖无关。

On this day, tomb sweeping is one of the most important and popular activities to show respect to ancestors.

在这一天，扫墓是最重要、最受欢迎的祭祖活动之一。

After people were done with tomb sweeping, they would stroll around on grass, and this activity was called Taqing, which translates to stepping on the green.

人们扫完墓后，会在草地上散步，这个活动被称为踏青，意为踏着青草行走。
