The slavery museum is very rare, but this museum and slavery are also a little bit sideways, and it is simple to talk about the development and social style of some Yi civilizations, and you can learn something. 1. Location: halfway up the mountain, there is an observation deck overlooking the Bohai Sea; 2. Opening hours: 9 pm, 4 pm, can not enter after 4 pm, it is best to call before going. 3. Price: free; 4. Features: (1) divided into different museums to tell the generation, development and end of Yi slave system, and its cultural and civilized characteristics; (2) The disadvantages are more than the advantages, the museum in the 1980s is very old, the walls are quite tattered; the planning is unreasonable, each museum is very small, you can see it at a glance, divided into different categories such as sacrifices, lacquerware, etc., in fact, you can learn very little; The expression is simple, many are a painting on the wall, there is no real thing, it is better to go back to check the mobile phone, the painting is folded, the view is poor; the museum only opened 5 current, few and rough. I have been to the worse museum, the disappointing place, 2 stars can't be more.
