The surface is also more rugged, with fewer flat areas to land.

From Sunday: China lands craft on lunar surface
China’s Xinhua News Agency said the landing site was the South Pole-Aitken Basin – an impact crater eight miles deep and 1,500 miles wide – which is thought to have been created more than four billion years ago.
It is the oldest and largest such crater on the moon, so could provide significant information because the original impact may have ejected materials from deep below its surface.
