The blue sky is clear and penetrating, the white clouds are within reach, and the colorful sutras accompanied by the white Hada fly with the wind, turning the tube to the old heaven and earth, a pious pilgrimage on the way to the destination of the Potala Palace. The Potala Palace is a holy place of Gelug Tibetan Buddhism. It can almost be seen as a place where you have to punch in when you travel to Tibet. There are numerous pilgrims and tourists coming here every year. Whatever the beliefs of those who come here, that sense of sacredness arises when they are in it. It was built on the hills with great momentum. The words at this moment can not show the beauty of that time. It is said that the palace has survived wars and natural disasters. It is really impossible to imagine its original appearance, the thousands of years of waiting.
