Do you know something about Mount Tai ?   Yes . But not too much . It is considered as the head of five sacred mountains in China .   Five sacred mountains ? Why people call them so ?   Because in history , the Chinese emperors used to climb onto these mountains and pay tribute to their ancestors and pray for good harvest and prosperity for the whole nation .   Got it . Can we see any things left by them ?   Definitely . There are many wall paintings and inscriptions on the huge rocks on the mountain .   I want to see them . How can I go there ?
