There was a group of men playing traditional musical instruments at the lobby when we arrived. After buying the tickets, a staff took us around the museum and explained the exhibitions, walls and even the buildings/statues in the garden.
It was a well-curated museum and the staff was knowledgable. The museum seemed to be popular with school kids so you might want to avoid weekends. We visited on a Monday and there was only one group of school children.
