Is it better for Nanning to travel to Xi 'an by itself or with a group?

As we all know, Xi 'an is the ancient capital of 13 dynasty, so most of the scenic spots in Xi 'an are ruins, and history is a very important aspect. If you want to know the city well, you need to know its history, so it is most direct to see what the ancients left behind. At this time, the tour guide plays a very important role.

Such as Terracotta Warriors, Huaqing Pool, Shaanxi History Museum, etc. These scenic spots have profound cultural connotations. So I think it's better to join a group.
