I want to go to Pinyao, but from where I live now (Siping) it seems the only way is to get to Datong first. Please, who knows how to get from Datong to Pinyao ancient city. And one more question, if I come to Datong, how to get to these famous Yungang Grottoes? is hanging monastery near or do I have to movegrom grottos to some distance?
