There are so many people in Xi'an, and it's really hot. Fortunately, the Terracotta Warriors are now equipped with air conditioning, so the temperature is acceptable. However, queuing outside in the 40-degree high temperature is really unbearable. The tour guide service is also very good, humorous and interesting, but the headphones are always interfered with, just like the Six Meridians Divine Sword, sometimes working and sometimes not. There is nothing to say about pits 1, 2, and 3, and I feel lonely after seeing it.
