1)I will be in X'ian around 22/23 May and need to know if the Terra Cotta museum is ever closed on certain days--I don't want to miss it by arriving on the day it is closed (as I experienced with some museums in cities in Europe)
2)I am also interested in seeing the Nestorian black stone stele about the seventh century mission of the monk Alopen to China which i believe is also in X'ian. Does anyone have info on that?
