The main functions of this palace, built by Songzan Ganbu, the Tibetan king in the 7th century A.D., include the political center of Tibet and the Tibetan Buddhist center. Later, it was renovated and expanded several times. That is to say, it is now the appearance of the Potala Palace. If small partners come to the Potala Palace, they are advised to familiarize themselves with it first, so as to avoid embarrassment.
