In travel, there are some interesting observations.

1. The reason Yong'an Zen Temple has been preserved is that the main hall served as a granary during the Cultural Revolution, which allowed the murals from the Yuan Dynasty to be kept, although they still show various signs of wear.

2. The Hanging Temple was able to survive because during the Cultural Revolution, it was directly dedicated to Chairman Mao. To break the Four Olds meant to defame the Chairman, so it was preserved.

3. The reason Jin Shrine has been able to be preserved is that it was designated as a protected site in 1961 due to directives from above, and at that time, Shanxi was focused on steel production.

4. All the ancient buildings being renovated are basically from the Ming and Qing dynasties, and it is unlikely that anything remains completely intact.

The Cultural Revolution often destroyed places that were rich in cultural symbols but had low political weight; Shanxi does not belong to this category.
